Size of the backup set

• Big increase in size of the backups after upgrade

  Hello

  I updated my database of 10.2.0.4 on win2003 SP2 for 11.2.0.1.0 SE SE on win2008 R2 SP1 64 - bit, by making exp/imp

  The amounts of size databasefiles up to approximately 150 GB on each server

  But when I do a normal RMAN backup of the data files to the new database (database backup device type disk); I get a backupset that is 78 GB in size.

  On the old database, the backup size was only 36 GB

  Two data are substantially the same, and I don't think I'm using the compression on any one of the database backups. I listed the RMAN settings below

  Can someone tell me why I see this huge increase in size of the backups?

  Best regards

• The total size of the backup database and Total database size.

  Hi Experts,

  Hello

  See this doc...
  http://download.Oracle.com/docs/CD/B28359_01/backup.111/b28270/rcmreprt.htm#CHDBIGHG

  Connect to SQL * for the database you intend to question the backup history.

  Ask the view V$ RMAN_BACKUP_JOB_DETAILS for more information on the backup type, status, and the start and end time.

  The following query shows the history of the backup jobs sorted by the session key, which is the primary key for the RMAN session:

  COL STATUS FORMAT a9
  COL hrs    FORMAT 999.99
  SELECT SESSION_KEY, INPUT_TYPE, STATUS,
         TO_CHAR(START_TIME,'mm/dd/yy hh24:mi') start_time,
         TO_CHAR(END_TIME,'mm/dd/yy hh24:mi')   end_time,
         ELAPSED_SECONDS/3600                   hrs
  FROM V$RMAN_BACKUP_JOB_DETAILS
  ORDER BY SESSION_KEY;
  

  Ask the view RMAN_BACKUP_JOB_DETAILS V$ at the rate of tasks of backup in an RMAN session.

  The following query shows the speed of backup job sorted by the session key, the primary key of the RMAN session. The in_sec and out_sec columns columns display the input data and output per second.

  COL in_sec FORMAT a10
  COL out_sec FORMAT a10
  COL TIME_TAKEN_DISPLAY FORMAT a10
  SELECT SESSION_KEY,
         OPTIMIZED,
         COMPRESSION_RATIO,
         INPUT_BYTES_PER_SEC_DISPLAY in_sec,
         OUTPUT_BYTES_PER_SEC_DISPLAY out_sec,
         TIME_TAKEN_DISPLAY
  FROM   V$RMAN_BACKUP_JOB_DETAILS
  ORDER BY SESSION_KEY;
  

  Ask the view RMAN_BACKUP_JOB_DETAILS V$ for the size of the backups in an RMAN session.

  If you run the DATABASE BACKUP, then V$ RMAN_BACKUP_JOB_DETAILS. OUTPUT_BYTES indicates the total size of backup games written by the backup task for the database that you are backing up. To view the backup set sizes for all registered databases, ask RC_RMAN_BACKUP_JOB_DETAILS.

  The following query shows the speed of backup job sorted by the session key, the primary key of the RMAN session. The in_sec and out_sec columns columns display the input data and output per second.

  COL in_size  FORMAT a10
  COL out_size FORMAT a10
  SELECT SESSION_KEY,
         INPUT_TYPE,
         COMPRESSION_RATIO,
         INPUT_BYTES_DISPLAY in_size,
         OUTPUT_BYTES_DISPLAY out_size
  FROM   V$RMAN_BACKUP_JOB_DETAILS
  ORDER BY SESSION_KEY;
  

  The following sample output shows the speed of the backup jobs:

  I hope this will help...

• As a Time Machine backup, it keeps adding to the size of the backup?

  TM starts the backup and starts suddenly to add to the size of the backup, it will do. This means that no player will never be large enough to accommodate the backup because it keeps growing in size (as each block of data is added, the size of the backup continues expansion of the same amount). I have attached 2 screenshots showing what has happened in the minute to restart the backup. TM is backup on an external WD hard drive via the USB-3 port on my MacBook Pro (retina, 15 inches, end of 2013). 1.9 TB of data backup - there should not be a problem because the external hard drive has 3 TB of space and has been freshly formatted before being used for the first backup on this drive. As you can see from the screenshots, the backup is much larger than it should be.

  

  1 minute later screenshot:

  

  Before this behavior, I have had problems with Time Machine while using another backup drive (a drive LaCie Quadra) with for example, ignored backups, backups landed at calculation time, backups, partially blocked by a backup for more than 36 hours etc., error messages from read-only TM etc... I tried several solutions on this forum and none seem to have corrected these strange behaviors. It felt like I've solved a problem, shortly after another was about to begin.

  I stopped finally try the solutions suggested here in the forums, as well as some external sites such as Pondini and chose to use another drive (HD freshly cleared using disk utility - the WD drive that is currently attached to the MBP). The WD external drive worked well on the Mac Pro in the office, and I have no reason to suspect that this is the problem (I ran some tests after erasing it and there is no error reported).

  Well, the first symptom that something still was wrong was when backing up to disk WD has slowed to a crawl yesterday afternoon, but I left it on overnight. At noon today the backup was still running, but about ⅔ complete (very, very slowly - running data blocks are moving into very small pieces), but I have to bring the MBP to a meeting and everything stop. Then my back and everything by plugging, TM started upward and all seemed well, until I noticed that the backup data was almost 2.5 to. I restarted the MBP. It's once again, I noticed that Time Machine did not work as I expected. The size of the backup continues to expand... I was expecting TM that she had about 250 GB left to save, but as see you from the screenshots it much much smaller than that. I have let it run like that for about 2 hours, hoping that it was just a small mistake, but the HD continues to fill, only 185 GB of space left. Strangely, I can enter TM and see my data.

  Suggestions please? Very much appreciated.

  Stu

  Nobody answered, so I thought I'd share the temporary solution I came up with.

  I started in safe mode, deleted the backup external TM drive I was using and launched a full backup with TM (always in safe mode). I leave TM turn all night and a full backup has been completed. I rebooted, entered TM and restore some files to confirm that I was actually able to restore the backup pieces. Since that time, I did have problems with TM make scheduled backups, with one reading errors etc.

  I will continue to spend some time to know what triggered these questions... since I was able to make a backup in safe mode, this means that I have other avenues to explore.

  I will report back if I find anything.

• How to know the size of the backup through POS image

  Hello

  After you have configured vShpere Protection data, I run successfully backup jobs, but I can't find details on employment, the size of the backup image.

  is it possible to get it?

  I think that with the POS, it is pretty easy, I don't even know what the speed of the backup, backup image format, etc..

  To connect to vCenter through thick client. Select the POS device and goto tab «Tasks & Events»

  Now find the backup job id - see attachment file for reference.

  Now ssh to the POS device and run the following command. / * Don't forget to provide the id of the backup job in the command * /.

  grep-i "Logging" to/usr/local/avamarclient/var-proxy * /* vmimage?. Journal

  The command output contains the path of the log file of origin for the backup, which should contain complete information.

  Capture of the info from my log file (that you might want to watch)...

• Backup utility Windows 7 application ' are you sure you want to remove the most recent data from the backup file "even if I'm trying to remove the backup set is not the most recent.

  I'm trying to reduce the amount of space that my Windows 7 backup uses so I've come to the place in Windows 7 backup:
  Manage space > view backups...

  I am then presented a list of three backup sets:
  01/03/2012 to 01/04/2012
  12/07/2011 to 12/21/2011
  23/11/2011 to 30/11/2011

  I would like to remove the older two, leaving the most recent. However, this doesn't seem to work as expected. If I try to delete one of the two most recent ones (the first two in the list above) I get the following warning "Are you sure you want to delete this backup file.

  However, if I try to delete the last one in the list, I get a slightly different error "Are you sure you want to remove the most recent data of the file backup?"-sounds strange because it is clearly not the most recent backup according to the dates it's show.

  Of course, I can go ahead and ignore the warnings, but I fear that maybe there are some files in the last backup the value in the list that may not be right more recent set backs.

  In 2011, I thought this might be something wrong with the date formats vs US UK (I am in England so the above dates are in dd/mm/yyyy format and not in jj/mm/aaaa) - but now it's 2012 and I backup from 2012 and 2011 games and he always seems to think that the oldest backup of 2011 is the most recent.

  Any ideas? Can I delete the oldest backup sets (that is, the two that are from 2011) safely?

  Any help much appreciated - thank you.

  Update: I checked on other PCs in the office and the situation is the same - is not only something strange on a PC.

• HP Support Assistant asking to redo the backup set

  I already have backup/restore disks for my HP Windows 7 computer. He nagging guard make me again.  I tried to force and wastes 3 DVDs just to shut up.  Unfortunately, he knows I did the drive in the value!  How I locked this thing?

  OK, we need to remove the program from HP support first if you don't know how to do this, click on this link and it will show you.

  Once you see the list of programs, locate the HP support assistant do a right click on it and left click on uninstall, it is a fairly large program, so it will take a while.

  Once this is done, restart the computer, once the computer is to click on this linkand press the download button to start the installation. Now, there is a good chance it will prompt you to repeat disc only because it is a new version of the software. If it follows the screenshots below to get rid of it: If the message comes up it will be under the HP messages section.

• Is it normal for a backup catalog LR CC 2015 to substantially reduce the size of the file?

  I just noticed that my backup LR CC 2015 declined substantially in size - 2.68 GB on April 22, before the LR 5.7 upgrade, now up to 432 MB may 6. Is this normal? The main catalog on my drive C (37.3 GB) seems to find any image file that I ask instantly, go back up to 2007. So I think that my master catalog is very well after the automatic upgrade. Is the reduction of the size of the backup because it can see my pre - LR CC 2015 backup (made under LR 5.7) in the same backup location and only backup the news since April 22? A kind of differential backup, perhaps? I normally delete old backups and just keep the last two – I'm reluctant to remove a 2.68 GB and rely on a much smaller. Any thoughts on this please?

  LR 6 and CC 2015 use ZIP compression. If you look at the Catalog backup file is the extension ".zip". My catalog LR 5 file went from 1.0 GB to 98 MB, or 1/10th the size!

  Open the file OWNER-VAIO in my external hard drive, I find several games backup over the past two years. They are responsible for close to filling that 500 GB hard drive. I have to keep each backup set? I have a set of 3 Sony recovery discs, made for me by Best Buy when I bought the laptop. These recovery disks are redundant backup sets to a certain extent? Please, someone, tell me if I can free up space on my external hard drive by deleting all (or part) of these backup sets. Thank you!

  I'm still trying to understand why I have to have as many backup files. I guess this is the Vaio Care that prompted backups several times this year (and also in 2009 and 2010). 2011 the only backup files have already taken over 160 GB of space on my external hard drive - a third of its available memory. Each year backup files are in a backup set. Can I get rid of the backup sets for 2009 and 2010. And some of the files earlier in the game this year?
  What all because I can't say Vaio Care I have a set of recovery discs, made for me when I bought the laptop? Vaio Care report saying me that I have no recovery discs. It would help if I advanced (in Vaio Care) and made another set of recovery disks?

• What are the contents in the backup of iPod touch 5G on iMac with iTune?

  I just made a backup of my iPod touch 5G on iMac with iTune, to my surprise, after the backup, I check the size of the backup copy, less than 1 G, and my iPod touch its use is more of 10G. So wonder what content on my iPod touch were backupped? I thought that all the APPS, iBook, materials, Photos, Podcast materials would be included in the backup, seems they aren't, otherwise, my backup folder may not be less than 1 G.

  Thanks for your help and sharing
