Snapshots vs Backup

Similar Questions

• Remove orphaned snapshots of backup failed

  ARCserve backup software is a failure while trying to back up virtual machines and leaving behind the clichés that are deleted. I work with CA (ARCserve) to solve backup problems.

  I have a few virtual machines in need of consolidation and others who don't. Can I just do a "remove all" snapshots on these virtual machines or do I consolidate those in need, first of all?

  Thanks in advance.

  Hi Jim,.

  Both delete and consolidate would eliminate them the snapshots, IE do it connects and validate data on the basic disk (VMDK). I'd rather have the virtual machine under tension, then go with consolidation,

  Since we can not estimate on when it can be completed.

• Snapshot with Exchange 2007 and AD backups?

  Hi all

  I was wondering if best practices in ESX4 changed regarding snapshots for backups go. Is still a bad idea to take a snapshot of your Exchange and AD server? As I know that in the last restore from a snapshot in a situation of failure total was not recommended for AD or Exchange. This changed at all or anyone has tested this more in detail?

  Also as far as backups go it is always advisable to make an announcement file level backup and exchange with your agent of backup software (IE. Backup Exec Agent 12.5 Exchange / AD agent, ect)

  A lot depends on how you have the Exchange Setup program.  You have your database and logs on the VMDK files?  RDM?  All these things will make a difference on how you protect the virtual machine.  In my view, there is no size unique all the backup strategy for virtual machines and applications, so it depends on what your environment looks like.

  I have the environments that use snapshots and vRanger to connect to VMS Exchange backup.  But the restore strategy depends on what actually happens to know which method is used for the restore.

• snapshots and dynamic disks

  All,

  VMware documentation States the following:

  • You can not go back to a snapshot with dynamic disks, so suspended snapshots are not used when you restore dynamic disks. Snapshot technology has no visibility into the dynamic disks. Dynamic disks are generally known as specific files of Microsoft systems.

  Dies of what it means that they are not supported at all, or just suspended snapshots are not supported? What confuses me, is that the snapshot technology has no visibility to dynamic disks.

  Well, that needed to be corrected.

  According to vmware:

  Do not use the VMware snapshots for backup of dynamic disks. If you take a snapshot of a dynamic disk (specific Microsoft file system), you will not be able to go back to the snapshot. Snapshot technology has no visibility into the dynamic disks and is unable to preserve the State of suspend to disk files.

  Read this: VMware vSphere 5.1

  So the overall production is no snapshot will be supported in dynamic disks that the State called 'suspended' will not effect and can not make any changes it all by making the previous snapshot version.

  Hope you guessed it.

  Thank you

• Máquinas backup tolls (vmdk)

  ESSA e minha first post here.

  USO em meu ambiente o vShpere 4.1 essential more com 3 hosts ligados dell equallogic 2 da (isci). Also I have a Cisco Small Business
  NSS326 smart storage. A backup of nor realize e do vmdk nesse ja esta em meu ambiente do storage.
  Gostaria to throw some doubt em Relaçao ao das backup maquinas tolls (vmdk).
  Sober pesquisar as tools e depois possibilidades para essa has fiquei com some questions.
  A fazer minha ideia era first try no segundo of snapshot storage. Depois of rel e o funcionamento snapshot (as backup e nao) understand, studioso a worm other alternativas.
  Then then a worm sober o VCB. No comeco seria algo me atenderia, sober mas a top com o meu software backup nao go funcionar. Ultilizo Bacula para o backup back dados das Máquinas.
  Also as a descontinuou o VCB VMware vi. É ISSO mesmo?
  Comeei agora a little a sober o ler Data Recovery. Can not use ele com a minha essential licensa more?
  It will be than can fazer algo como comentei acima com o Data Recovery.
  Desde ja Agradea§o e gostaria "is nao for too pedir" some e tips contact us sober essa backup strategy.

  Bem Vindo...

  Realmente o você disse esta certo, Snapshot backup, snapshot o e nao serve fazer para any configuracao, instalacao, UO atualizacao Sistema operational quando vai da Máquina virtual, assim você drew instant uma da Máquina virtual realize essa mudanca por Segurança, wave seria o ultimo estado antes da Máquina virtual integra.

  O SIM VCB esta descontinuado e no lugar entrou o VMware Data Recovery, that alias e better than o VCB em terms of use, POIS você tem um plugin that integra ao Center Virtual, that facilitated muito.

  SUA licença provavelmente use VMware Data Recovery ate wave sei o suporte da, mas confirmed through aba do VMware Configuration > has a license, deve ter VMware Data Recovery nessa relaçao.

  O Backup Data Recovery e feito a nivel VMDK e ele nao raised Informação duplicada, isso e bacana, nao levar o disco inflado alem. (EX: VMDK 100 GB, 20 GB, ele leva only os 20 GB used).

  Você do use da forma than esta commenting no post sem nenhum problema.

  Specific case of ajuda told me, mas pra você e mesmo o VMware data recovery option best.

• VDR & VCB Snapshots

  VCB creates a snapshot named BACKUP VCB and VDR creates a snapshot named datarecovery .  When using VCB, if I already have an existing snapshot with the same name as the VCB creates, the creation of the snapshot fails. But VDR is remove the snapshot and creating a new, if she identities already existing snapshot named datarecovery . No explanation for this?

  That is right.  We pictured "datarecovery" as a single word could be quite unique not happen accidentally.  As you mentioned, this may have been a bit naïve.  However, please avoid your shots manually generated names like "datarecovery.

• Storage and snapshot space views

  Hi all

  Among the new features of vSphere is the tab "storage views."  Click on an object in vCenter (for example, a cluster) and then click on the tab "storage views."

  This tab includes useful information on the topic, including the amount of snapshot space which currently consumes each VM.  This is a great way to eyeball a cluster quickly and see what virtual machines are currently a snapshot.

  My question is not a big problem - more a curiosity.  When I look at the tab "Storage views" I can see all virtual machines running on this group.  None of my virtual machines currently have a snapshot.  However, the amount of snapshot displayed for each virtual computer space varies.  Even say 1.08 KB, others say 633 B etc.  About three quarters of my virtual machines have a very low value like this (1 KB or less) with the remaining quarter actually list 0 B.

  I would have thought that any virtual computer without a snapshot must be 0 b.

  As I said, this isn't a big problem - just a curiosity.  It is still pretty easy to tell who the virtual machines have a real snapshot that you can ignore all those containing 1 KB or less space snapshot.  I expect always all VM without a snapshot to show 0 B well and I consider it a (minor) bug.

  Does anyone else get these strange numbers?

  See you soon,.

  Did a little research on our environment and I think I know what you saw, we have a few shots in our environment but also show some VMs who have no snapshot with the display of 1.08 KB on the view of storage under use of snapshots, then I guess that its getting this information based on files located in the directory of the virtual machine. What I found to a specific VM has been there is a filed with an extension called .vmsd that contains the metadata about snapshots, also defined on VMwares Web site: http://www.vmware.com/support/ws5/doc/ws_learning_files_in_a_vm.html

  The size of the meta file:

  [root@himalaya Quentin]# ls -lha | grep .vmsd
  -rw------- 1 root root 1.1K Jul 12 08:18 Quentin.vmsd
  

  This metafile looks like the following (which I remember creation but via the CLI):

  [root@himalaya Quentin]# cat Quentin.vmsd
  .encoding = "UTF-8"
  snapshot.lastUID = "127"
  snapshot.numSnapshots = "0"
  snapshot.current = "0"
  snapshot0.uid = "127"
  snapshot0.filename = "Quentin-Snapshot127.vmsn"
  snapshot0.displayName = "BackupShot"
  snapshot0.description = "Snapshot for Backups"
  snapshot0.createTimeHigh = "290435"
  snapshot0.createTimeLow = "-1325916361"
  snapshot0.numDisks = "1"
  snapshot0.disk0.fileName = "Quentin.vmdk"
  snapshot0.disk0.node = "scsi0:0"
  
  snapshot.needConsolidate = "FALSE"
  
  snapshot1.uid = "101"
  snapshot1.filename = "Quentin-Snapshot101.vmsn"
  snapshot1.parent = "100"
  snapshot1.displayName = "Snapshot-2-8:45"
  snapshot1.description = "8:45am snapshot"
  snapshot1.createTimeHigh = "287640"
  snapshot1.createTimeLow = "-1172553953"
  snapshot1.numDisks = "2"
  snapshot1.disk0.fileName = "Quentin-000001.vmdk"
  snapshot1.disk0.node = "scsi0:0"
  
  snapshot0.type = "0"
  
  snapshot1.type = "1"
  
  snapshot0.disk1.fileName = "/vmfs/volumes/48e91a93-a0a8d3bf-f831-003048670887/Quentin/Quentin.vmdk"
  snapshot0.disk1.node = "scsi0:1"
  
  snapshot1.disk1.fileName = "Quentin-000002.vmdk"
  snapshot1.disk1.node = "scsi0:1"
  

  I also look at other virtual machines that are not instant and the size is more properly associated with it real snapshot deltas, although virtual machines without the clichés that the size of the .vmsd seems to fit with what is shown in the view of storage that you noted, these virtual machines have no snapshots. I think that if a virtual machine has snapshots at any given time and was afflicted with consolidation or remove, the .vmsd could not have been cleaned and then used as a benchmark as "thinking that it snapshots and uses the file size of the .vmsd.

  This hypothesis was fairly easy to test, what I did to remove Quentin.vmsd (the virtual machine has been turned off, may want to be careful when his online) and what you need to do, is not to update the display of storage, but go to the virtual abstract machine and do a refresh on the use of the storage. This will refresh the specific data store on which this VMs lived on and if you return to the storage view and put a refresh/update, you will notice that the size of the snapshot goes to 0bytes now, which is pending.

  So I think that explains which continues, perhaps a quirk or expected behavior. Yet once again, I agree that suits you just look for the use of delta< 1gb="" for="" real="" snapshots="" or="" you="" can="" always="" go="" in="" and="" clean="" up="" the="" .vmsd="" files="">

• General issues for the backup servers.

  So, I'm new in the world of VMware and have a few questions about having a configuration of spare warm in case something breaks down.

  There are two main things I want to know...

  1.

  We have a Vmware box currently implemented with 2 VM on it (I did not)

  upward). We would like to have a server of spare ready in case where that crashes,

  but without spending too much money. Wouldn't be better to set up ESXi

  on the wheel of relief and, in case of failure, use the images on hand

  to bring them up, temporarily, or to have a server spare and just

  take the disks on the server down and drop them

  replacement part (assuming it wasn't a disk failure). Or the other of these works would be?

  2.

  Is it possible to take snapshots of machine non - VM and use then

  images in VMware to save in a virtual environment until the

  physical server is repaired? Just curious.

  Advice or tips would be greatly appreciated.

  Your best bet would be to have to install ESXi on the other server and images of current virtual machines to run on your existing server that are taken periodically. I guess that the tone of the email, that you do not have an overabundance of funds to work with, before storage, shared clustered and snapshot based backups would be off.

  If you rely on the possibility of recovering virtual machines among readers on the existing system, you may be in for a surprise.

  Answer brief No..

  Long answer, you can do one or two things that may not work. You can sometimes ghost physical systems and then you may be able to restore the system as a virtual machine image ghost. You might be able to restore a backup image to a virtual machine, and then fix it to a working state.

  There are a number of options available and I'm sure that some other people will be piling on short time

• Songs missing in iCloud

  I bought an album containing 20 songs from back in 2012.  The reception in iTunes confirms 20 songs.   However, when I look under "purchased" in iTunes, I don't see that 14 songs.  Also, I can only download 14 songs on the new features.  I remember very well being able to play all 20 songs for a while.  So either my list of "bought" in the cloud has been corrupted at some point or Apple no longer has the missing songs (in which case I'm afraid there is not much I can do).  The album is no longer in the iTunes store.

  Fortunately, I still snapshots and backups of the album original 20-song, but I still want to solve this problem.

  Thanks in advance.

  You have checked to see if you have hidden tracks of the Cloud: hide and expose the purchases made on the iBooks Store - Apple Support, App Store or iTunes Store ?

• Half of the memory is the other?

  I use a MAC Air just to have around when traveling. There is no files (documents, music, movies...) on this subject. All I have are normal applications. I see that 'other' took up to 16 GB of memory. How to remove the "others"?

  There are local backups. Your Mac creates "snapshots" of backup when you are not connected to Time Machine. You can check with Omni DiskSweeper it can show you the exact size and location of all your files. It will be the inventory of your disc from files that occupy more space. It can also give you a fairer read disk space than the Finder or storage tab of the about this Mac. If you want you can even delete files from OmniDisk Sweeper.

• change drive for time machine

  I take my macbook pro travel and I am currently using an external drive for backups time machine, how to choose the hard drive to the mac for the back upward?

  If you want to save your MBP via Time Machine, put the HARD of Time Machine disk with you.  Now time Machine will store snapshots as backups automatically, but I wouldn't count on them:

• Recovery of free space Compellent

  Hi guys, I installed a new Dell SCv2020 Compellent storage with vSphere U3b 5.5 for an existing customer

  I have a deep knowledge of Dell PowerVault storage, but I'm new with Dell Compellent. I read that the snapshots for backups or running Storage vMotion can affect free space on the end due to the native LUN provisioning storage: communities.vmware.com/.../436628; TSTART = 0

  The suggestion is run or plan the command "esxcli storage vmfs unmap-l MyDatastore" which calls the primitive SCSI UNMAP manually

  I tested a Storage vMotion and indeed space on the source LUN are assigned until this only manually 'no '. I have not yet tested how instant backup affect free space on the storage because I've not yet migrated any VM on the new infrastructure (by the way I use v8 of Veeam Backup who insist a lot about VMware snapshots)

  Anyone here can share ideas and comments? Thanks a lot guys

  Marco

  You are on point, use the tool unmap to reclaim space on the LUN. Compellent thin provisions at the end back and depending on your environment, you should probably be thin provisioning your LUN on the end of VMware. To the wire when you remove VMware servers and vmotion of data store to data store space, will not be recovered on Compellent b/c, that storage is ignorant because data are only is more used. The "fix" for what there is complete integration between VMware and Dell is to run that unmap tool.

  What started doing every quarter or so is to run the tool unmap on all LUNS that are thin and put into service (in our environment all volumes). I tested unmap several times and I had no problems with running the tool while the servers are running on this volume. I would say that the tool running on a server that does not have a lot of load work because the CPU spike during unmap (datastore readings will boost as well).

  Regarding backups and snapshots, I have no problems with the space about those. Replays freeze blocks of reference data, but once this review has expired the space is recovered. Regarding backups depends on what you use for backups - we use CommVault who will take a glance of the LUN, copy the data off power then release the tension (so for a short period of time, he didn't there ate during the backup space, but it takes a few minutes to copy the data).

• E.M.P. automate Upload File to FDMEE

  Hello everyone,

  Download the data to FDMEE using EMP file automate where can I find the file in FDMEE?

  I don't know why you don't spend time reading documentation, but take a look at the following example, because it gives an idea of the location - https://docs.oracle.com/cloud/latest/pbcs_common/CSPGS/apas06s07s02.html

• Archivelogs is not being removed to apply.

  Environment: Enterprise DB 11.2.0.4g running on the virtual machine. I have a production system with a Data Guard physical standby working.

  What I want to do is the day before the disk back and use our regular vm snapshot and backup (Veeam) to do the actual backups.

  In my tests, the two systems have been implemented with RMAN

  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED PENDING ALL THE

  However, archivelogs continued to accumulate on the production system until I forced a backup it via RMAN. (Note the FRA limit was set at 4 GB, at the time wherever I forced backup reached 26 GB!) Once I made the backup, applied logs have been deleted.

  How can I tell the production system to really, Yes, I mean, delete the archivelogs when applied!

  This is the result of a show all in RMAN:

  RMAN > show all.

  RMAN settings for database with db_unique_name PHMWEB_PROD are:

  CONFIGURE REDUNDANCY 1 RETENTION STRATEGY; # by default

  CONFIGURE BACKUP OPTIMIZATION # by default

• PowerCli mass command to disable a specific NIC on the VMS 2000 +?

  Hello.

  Small question

  We are running

  ESXi version 5.5U3 and Vsphere 5.5

  We have 2000 + VM with a specific network card called VLANXXX (normal vswitch - undistributed)

  It has been used for our former backup system which was IP based and is now is no longer necessary that we went to a snapshot based backup system.

  I have an excerpt from a list of all virtual machines with this this adapter in a CSV / text format

  for example

  Server1

  Server2

  Server3

  is it possible to generate scripts an order essentially watch the folder and then go ahead and 'Disconnect a nic VLANXXX' (both on the power and the current connected state)?

  Once its been disconnected and left it that way for a week. the plan must then run another script to delete this completely on each virtual machine NIC.

  I had a search around but was unable to find anything which could do this

  Any suggestion would be great.

  You can try something like this

  $pgName = "VLANxx".

  $vms = get-VM-name (Import-Csv names.csv - UseCulture)

  Get-NetworkAdapter - VM $vms | where {$_.NetworkName - eq $pgName} |

  Set-NetworkAdapter-connected: $false - StartConnected: $false - confirm: $false
