Good size of disk RAID 1 for Time Machine

• What is the best solution when my external drive for Time Machine is full?

  Hello

  I use the latest version of Mac OS X on my iMac 27 ". I use a drive outside of 3 TB G-Tech for Time Machine backup. Due to my recently many RAW photo images, I have less 8% left storage on my external hard drive, so I'm trying to figure out next steps in what concerns the strategy of external storage and have the following questions:

  • When my external drive for Time Machine is full, it is my understanding that older backups on external hard drive will be deleted to make room for newer backups. If the oldest backups contained pictures (whose records have not changed since the time they are initially stored), then I guess that these photos will be removed from the external drive - correct?
  • If I had to replace my external drive for Time Machine with a new external drive which is as big or bigger than the one it replaces, what should I expect on the size of the initial backup on the new drive? I guess the size of the backup would be exactly equal to the current amount of storage used on my drive hard iMac - correct?
  • Would it not be possible to connect the external drive for Time Machine existing at a new Time Machine external drive so that when the original disk is full, the overflow will be automatically stored on the new external hard drive for Time Machine? (If feasible, it seems that this strategy would maximize my external storage capacity vs just replace external drives.)

  I realize that my first two questions are rather basic, but I don't want to make any false assumptions. The third idea is intriguing and I would like to know if this is a viable option.

  Thank you

  older files are starting to get deleted because the disk fills up then Yes, they went

  the backup drive should ideally be 4 times the capacity of your current drive, twice is good but has its limits. Also factor in what you store: a jpeg from the web and a raw photo file are the two images, the size of a is very different. If you work in high-resolution or large native files, or audio files (record pro, no music files) or video production twice the disk fills up very quickly. If you collect photos and JPEG and mp3 files or a handful of videos not so much is necessary.

  I would keep the old drive intact if you want to replace and start over with a new drive, if that's the plan. You have the old data, you can keep it somewhere safe and have a redundant backup which you can reconnect at any time to restore from. Let the new index drive itself with new data and take if from there, in the case otherwise you can copy the backup to the new drive and set the drive as the new source of backup but personally I wouldn't copy of the data, that's my preference, it may not be yours and that's fine.

• Adding 2nd drive for Time Machine

  I have an IMac with a 3 TB drive and a 4 TB laCie drive Thunderbolt used for Time Machine. I get the message that the Time Machine disk is full. I can daisy chain a second LaCie and recognized it as an add-on to Disk Time Machine?

  Not unless your create a JBOD RAID array. You can * another player and change Time Machine backup on this drive. If the player has not been used for a backup Time Machine, then Time Machine will start a new backup.

  Note that you have to create the JBOD or RAID Stripe it would remove all files on both drives before you create the table. Thus, when selected for the drive Time Machine you will be a new backup.

  About alert TM "Backup Drive is full"

  TM only deletes older files if they have been removed from the source and when TM needs space on the backup to a new incremental backup drive. Time Machine "Jules Destrooper" its backups. over 24 hours, old backups, except the first of the day; These "dailies", old more 30-day backups, except the first day of the week. The weeklies are kept as long as there is room.

  So, how long a backup rest file depends on how long it was on your Mac before being deleted, assuming that you do at least one backup per day. If she was there for less than 24 hours, it will be maintained for at least a month. If she was there at least a week, it will be maintained as long as there is room.

  Note that, on a Time Capsule, the sparsebundle grows in size as needed, but not descended. View of the user of the TC so it seems that no space was released, although there may be space in the sparsebundle.

  Once TM has found that it cannot free enough space for new backup it reports the disk is full. You can erase the backup disk and start your backup or replace the disc with a larger drive.

• How much space for Time Machine backups

  Hello

  Is there a rule for how much space you may want to allow for Time Machine backups?

  I would like to partition the drive to have a room reserved for Time Machine back ups only.  I realize that it is a personal preference.

  Each individual backup occupies approximately 790 GB.  But somehow I have 6 months of backups that supposedly take up only 880 GB on the disk.

  At this time the backups of my other drive back to 6 months in time.

  Fortunately, I never had to go back a few more days to recover a file.

  Is there a reasonable amount of space to allocate for backups, based on current usage of disk?

  Thank you

  Minimum would, of course, the size of the internal drive.

  Double the quantity is sufficient

  Triple the amount if you want a value years from TM backups

  I am convinced that these are independent external drives from your main hard drive of Machines

• Want to format a disk and set up time machine

  Hi all

  I don't currently have access to a MAC, so yo please would undergo some basic questions?

  I have a client with a G-Drive 2 GB with NTFS.   I would like to format it for what is Time Machine friendly and configure for Time Machine.  Could someone point me to the proper indication?

  How to partition and format the disk and what (FS) file system should I use?

  I see on the web when you plug the thing, get you will invite to time machine.

  1. consider a Mac and then see #5.

  2. see #5.

  3 Time Machine is present on every Mac running 10.5 and newer.

  4 elements of it are in system preferences, then the Applications folder.

  5. Yes, you will be. Time Machine manages the process of formatting before the first backup.

• How can I know if an external drive has been used for Time Machine and what computer it came with too?

  How can I know if an external drive has been used for Time Machine and what computer it came with too?

  I have several laptops and iMacs. I spent the relocation of the year and only used the MacBook Pro.

  Now I'm trying to figure out which drive goes with which computer

  I connected just a disk seagate 1.5 t and the first thing he did was to ask if I wanted to use it as a Time Machine drive.

  (1) if it is the TM disk accompanying this computer don't would not it have just started upward automatically?

  (2) what happens if I would have said yes?

  (3) I don't even know if it's been activated for TM. Is there a way to tell? It may hold just for iMovie files and other programs associated with a computer from my past.

  All readers of backup Time Machine contains a folder named: Backups.backupdb. If you open this folder, you'll find another folder with the name of the computer that has been saved. If several computers have been saved on the same disk, you will have several folders.

• Should what format I use for my external drive for time machine?  I have a WD 2 TB that is formatted for PC new drive.

  Should what format I use for my external drive for time machine?  I have a WD 2 TB that is formatted for PC new drive.  When I got to disk utilities to erase, and then reformat the options are

  1 mac OS extended (journaled)

  2 mac OS extended (journaled, encrypted)

  3 mac OS Extended (respect for case-sensitive, journaled)

  4 mac OS extended (case-sensitive, journaled, encrypted)

  See the information below If you can not back up or restore your Mac with the help of Time Machine - Apple Support

  When you select a drive to use with Time Machine, your Mac automatically prompts you if you need to reformat the drive.

  • If you are using an external drive connected to your Mac, use disk utility to make sure that your backup disk is formatted in HFS + extended (journaled) and is the partition type GUID Partition Table (GPT).
  • If you use a time Capsule, formatting the drive for Time Machine preferences automatically formats the drive as HFS + Extended (respect for case-sensitive, journaled) with a GUID Partition Table (GPT).

• You can use a zip for time machine drive?

  I know he said 'external hard drive', but do not know if this means that you can use a zip for time machine drive? (including so you can back up your entire OS, but also files)

  Probably yes, but just wonder how to connect ZIP drive to your iMac.

  Hello, I'm looking for time machine to my iphone more than 6

  There is no time Machine to an iOS device. They are saved to the iCloud or iTunes on a computer; Time Machine can then save the backup to a computer, but he can't save a device iOS directly.

  I have finally reached my backup via Time Machine, it was temporary unavailable yesterday.

  Thank you guys!

• Cannot remove old Time Capsule for time Machine destinations

  My MacBook Pro moves with me between my home office and the different clients that I visit. At home, Time Machine backs up a volume of Time Machine on my Xserve served to the network by OS X Server. I guess that for the Mac it looks like a Time Capsule, although in my case, it's a RAID 5 with 12 TB of capacity.

  The problem, when I connect to one network other than my home network. As you can see, the window from system preferences Time Machine offer 'Time Machine backup on 'Dominik AirPort Extreme' network', which is not actually present on any network. When I go home, Time Machine continues to try to save this destination does not exist and does not back up the volume on my Xserve. I have to manually switch for my Mac starting the backup on the Xserve again.

  

  How can I make my Mac forget this volume forever? A couple of system reinstalls, to the end that I use the Migration Wizard to copy the configuration of the system from a backup, have not helped.

  On the computer of my wife as a backup destination appears, the good pair:

  

  This simple procedure will erase your settings of the time Machine, including the list of excluded items. The backups themselves will not be affected. If you have a long exclusion list that cannot be easily re-created, you may prefer a procedure more complicated that maintains the list. In this case, ask for instructions. If not, see below.

  Please triple - click anywhere in the line below on this page to select:

  /Library/Preferences/com.apple.TimeMachine.plist

  Right-click or Ctrl-click on the highlighted line and select

  Services ▹ reveal in Finder (or just to reveal)

  of the menu.* contextual A Finder window should open with a selected file. Copy the file to the desktop. Bring the original (not copy) to the trash. You will be asked for your administrator password.

  Restart the computer and re-create your settings in the Time Machine preferences window. Falsely, it will show that you have no backups. Don't worry; your backups have not been affected.

  Perform a backup to test. The backup can take much longer than usual. If TM now works as expected, delete the file that you copied to the desktop.

  * If you do not see the item context menu copy the selected text in the Clipboard by pressing Control-C key combination. In the Finder, select

  Go ▹ go to the folder...

  from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

• Independent external drive for Time Machine backup

  Can I save two external hard drives independently in two separate backup drives?

  2 TB DHM supported with a 2 to DHM

  and

  5 to DHM supported with a to 5 DHM

  The 2 TB drive holds the content inventory which changes often but never amounts to more than 300 GB.

  5 TB disk holds archived folders which adds, with about 30 GB of data, once a month.

  Time Machine is not really suitable for this. The only way I can see it could do would be to an installation to be excluded from the backup disk, then do the backup Time respective Machine. Then return the exclusion so the opposite road is excluded, then backup to the backup Time opposite Machine.

  This should be clear would be a completely manual process, in fact you realistic would switch off the Machine in time to avoid that it auto backup on the drive bad between manual backups.

  However other backup programs more sophisticated pourrait be configured to do this automatically.

• I would like to add a folder of photos on a USB key for time machine backups

  I have a new time capsule, and I am attaching a USB hard drive that previously held some my time machine backups and all my photos. I would now add the photo of backups auto time folder machine on the time capsule. But in time machine preferences I don't see the folder or the USB key. Although I can see the USB in the finder as well as the time capsule window. I can copy and paste the photo time capsule file it's just I wanted to time machine for backup for me. Any help much appreciated.

  The time Capsule is what we call a 'network' of the road, so when the USB is connected to the time Capsule, which would make it a "network" drive as well.

  Unfortunately, Time Machine is unable to back up a 'network' of the time Capsule drive.

  If you want to save the data or the USB disk using Time Machine drive, you will need to connect the drive directly to your Mac and then it will be saved with your Mac... assuming that the drive has been formatted for Mac to Mac OS extended (journaled) format. Then, the player will become a "local" drive

  If you need to keep the USB connected to the time Capsule, the only way to back up data automatically on a schedule would be to use a commercial program like Carbon Copy Cloner or ChronoSync.

• My Time Machine is full. Should I keep it plugged in and turned on even if I switch to another external hard drive for Time Machine backups?

  My external hard drive, Time Machine is full. Should I keep plugged in m and, even if I switch to another external hard drive to keep backups with TimeMachine?

  There is no need to keep two connected external drives. Instead, I suggest you to buy a bigger external hard drive and transfer the backups that you want from the old to the new external drive, so you can use the old external drive for other purposes-> Time Machine: how to transfer backups from a current backup disk to a new backup drive - Apple Support
