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

  • 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.

  • How to limit my Time Machine backup size?

    Hi, I have a 3 TB Time Capsule. My macbook uses all the 3 TB for backups. I would like to limit the size of the Time Machine backups to 1.5 TB and use the rest for my own files. Is there any setting or application in App Store to limit the size of the backups?

    Unfortunately no, if you ask on the backup using Time Machine.

    It is not officially supported by Apple, but you may be able to change the size of the space allowed for a backup by using this trick:

  • Search for Time Machine backups for email

    I need to get my backup files for a particular email. This backup is on an external hard drive but not in active service at the moment but plugged on my system for purposes of trying to locate this email and the ability to retrieve other emails stored with the hope of adding them in my active files.

    My current setup of the system is: internal HD: operating system and active storage, (OS X 10.8.5

    3 t external HD: Active™ backup,.

    4 t external HD: archive™ backups.

    Because I'm not sure how Mail stores the emails, I don't know what file (s) to search the Archives of Time Machine or if there is some way I can use the Time Machine application to access this file.

    Is it possible to access these archived files?

  • 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

  • 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.

  • Could not find the Time Capsule for Time Machine backup drive

    My iMac is running El Capitan and Time Machine is unable to find the Time Capsule backup drive.  I blew the backup several times in hopes that it will fix the problem.   The only thing I found which will allow a return to the top is to unplug the Time Capsule and plug it in again.  The work around works only once, then it's back to "can't find the backup disk.

    For anyone a cela or similar questions are you go in your Utilities folder (in your applications folder) and run the utility airport to see what he says about the disks attached. This cannot work for the readers of time capsule Apple rather than third party readers who have been designated as the backup time drives machine.

  • apply for time machine backup lightroom preferences

    I have a new iMac 27 inches. Previous (more recent) TM backup of my old computer could have corrupted some files (non-adobe software). Apple asked me to only migrate my apps (which I did) and then manually drag documents on. I configured CS6 and lightroom, but not the 3rd party editing applications I used as "Topaz", alien skin, and NIK came. In addition, all my preferences that have been recorded as watermarks, export settings, settings etc. of development are missing. I'm looking for files that I could drag during backup time machine to my new machine that would be the best possible save me Lightroom reconstruction from scratch. NOTE: I am able to access all my different cat files stored on external drives without problem. Just need to preferences back if possible.

  • How can I make Time Machine backup to an external drive?

    I have an external drive that I stay logged in all the time, and I want that she is saved with my hour of hard drive internal Machine. I found the setting "IncludedVolumeUUIDs" in Library/Preferences/com.appleTimeMachine.plist, but I can't change the permissions to modify.

    Open the Time Machine system preferences pane, click Options, and remove it from the list if possible. Time Machine can't back up NTFS, FAT32 volumes and exFAT.

  • How partition an external hard drive and configure for Time Machine backup?

    I am a rookie just to switch to Windows Apple Mac and I'm looking to back up my new iMac with a Seagate hard drive 2 TB external.  My Mac is a 1 TB hard drive, I'm looking to partition for backup and storage.  Is this a good idea?  Is there a simple way to do it?  I appreciate any help I can get.  I also bought three years of Apple support, but I'd rather do it myself, so I thought I'd give this discussion from the community to try.  Thank you!!

    No, it isn't. Your working data and backups must be on separate drives in case one of them goes down.

  • 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

    Brian

    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.

  • Drive Time Machine backup

    I recently connected my Mac online after a break of 2 years.  Once I upgrade the operating system, then connect the external drive for TIme Machine backup

    It kept failing.

    I then didn't back up the disk and now I see is no longer the external hard drive in the viewfinder view, but it appears in the system report > view USB.

  • Backup how much space do I need for a complete backup system?

    I intend to make a full system backup (complete with the image of the system) with a Toshiba 500 gig external hard drive I recently bought on Amazon.  I currently have 464,86 GB of free space available on this device (my external hard drive provided with the NTI EZ Backup utility).  How much space will create a full backup on this device?  Or should I simply back up files/folders and create the image of the system on a separate drive?

    Evan

    Hey Evan,

    It depends on the files and folders you have on the hard drive.

    For example: If you have 200 GB of a data value in the C drive then to perform a system image you need minimum of 200 GB of space on the external hard drive to make a system image.

    To learn more about the system image in Windows 7, see the link

    What is a system image?

    Should what backup settings I use to maximize my disk space?

  • I have my time capsule for base station; How do I set up just for Time Machine?

    For several years, I have used Time Capsule as a wireless base station more backup Time Machine. I back up a Macbook Air (single user) and iMac with 2 users (two computers running on OS X 11.5). With Comcast Xfinity I need is more like a base station. In fact, I reset my router Xfinity name and password to replicate what was the name and the password to my Time Capsule network. But, now that it's done I can't understand of set up time capsule without set it up as a base station. The installation guide seems to suggest that I could do so by plugging the ethernet cable from the modem to an ethernet port which is not the WAN port. But this configuration did not work. The installation wizard only took me the steps to set up a wireless network. How can I simply we it with Time Machine as an external hard drive?

    The installation wizard only took me the steps to set up a wireless network. How can I simply we it with Time Machine as an external hard drive?

    Simply turn off the time Capsule wireless.

    To do... Open AirPort Utility, click on the Time Capsule, then click on modify in the window that appears

    Click on the Wireless tab at the top of the next window

    Change the setting for the Mode of network on 'Off '.

    Click Update to save the changes

    But... and this is a big BUT... This work of pourrait ... and maybe not. Even if the backup on the Comcast network seems to be working, there will be no help from Apple in case of questions or problems of backup.

    The reason is that, so that your Time Machine backups be supported officially by Apple, users must save on the Time Capsule wireless, or connect their Mac (s) directly to one of the three ports LAN <>- on the Time Capsule using a wired Ethernet cable connection.

    If you decide to try the method of failure to load, please let us know how things work after a few days.

  • How can I restore mac Time machine backup to most recent?

    So, I recently met several problems with my old mac. He started acting upward with the blinking folder and question mark more often. So I did multiple time machine backups and have since then tried to reinstall the OS and many other options, but it looks like my mac middle of 2007 has had its day. So I bought a new mac and tried to restore the back upward on the external hard drive. I get the message that his back is an older version and it cannot be restored and I should use from the other mac migration assistant.

    So the question is: If the first mac is burned and I can not restore settings etc of the time external hard disk machine, how to restore the whole upward? Can I transfer files only?

    Very much appreciated.

    Hi Sir,

    You cannot restore data in time machine just like that. You use the data transfer assistant to recover your old records to your new Mac.

    The data that you used time machine made to your old mac are not available to your new mac. There is limitation of the system.

    Hope this could help you.
