"Backup is too large for backup volume" error

When I try to backup my StartUp Drive (931.2 GB capacity, 348.2 GB Available, 583.0 GB Used) to my Backup Drive (931.2 Available) which is mounted in the adjacent bay I have begun to get an Error Message that says "This backup is too large for the backup volume. The backup requires 1379.1 GB but only 931.0 GB are available." Clearly something is amiss. It was backing up to this hard drive just fine.
Here is the log from the Backup Buddy Widget

I installed a new hard drive ( replaced a 250 GB with a 1 T drive), I deleted a sparse image from another drive (neither of these drives were included with the backup from TM) and I renamed the TM drive from "Backup" to "2 Backup" after I erased it. I then attempted the full back up from the "Startup" drive to the newly erased "2 Backup" drive and got the error message. All drives are internal.
According to the messages you posted earlier, you're trying to back-up three drives:
Backup content size: 466.2 GB excluded items size: 0 bytes for volume 4 Movies
Backup content size: 583.0 GB excluded items size: 1.9 MB for volume 1 Start Up
Backup content size: 99.9 GB excluded items size: 0 bytes for volume 3 Media
That's a total of 1149.1 GB. TM then adds about 20% for workspace it will need (the "padding" in the next message):
Starting pre-backup thinning: 1.35 TB requested (including padding), 930.96 GB available
You need a bigger TM drive, or to back-up one or more of the other drives some other way, and exclude them from TM.
A 1 TB drive is just barely large enough to back-up your +Start Up+ drive, as TM really should have 2-3 times the space of the data it's backing-up.

  • Time Machine says backup is too large for backup disk -- but it isn't...

    I have a MacBook Pro with a 120GB drive and a 120GB external drive I use for Time Machine. Everything went fine for months until my laptop's drive got close to full (about 3GB of free space). Then Time Machine started saying it didn't have enough room to complete a backup: "needs 10GB but only 8.6GB is available"
    So I told it to stop backing up my iTunes movies (about 7GB). Still didn't work -- same error message (the actual values may have changed some, I don't remember).
    Next, I added another 10GB do the "do not back up" list. Still didn't work. Finally, I deleted (actually deleted, not just said "don't back up") about 5GB of files and emptied the Trash.
    Now it says it needs 15.9GB of space to do a backup and only 8.6 is available... ??? I've restarted the machine several times, still doesn't work.
    My solutions seem to be making it worse. Makes no sense to me.
    Any help would be appreciated. Thanks.

    Peter,
    Unfortunately, Apple hasn't documented this very well. However, those of us who know how Time Machine works behind the scenes know this to be true. Of course, Time Machine can back up a given machine at least once with only slightly more space on the backup drive than needed, but subsequent backups will fail.
    I have to disagree, though, that most people would fill a 250 GB hard drive. I have what I would consider a "just barely manageable" amount of data in my HOME folder, and my installation clocks in at about 100 GBs. Those "big ticket" items that would tend to bloat my HOME folder- iTunes videos, folders of huge images, etc.- I regularly place on some form of external storage when I no longer need them, removing them from my HOME folder. In fact, I have a partition on an external drive just for the storage of iTunes videos that have already been watched.
    If your installation is filling a 250 GB hard drive, you might consider your file management, and just what is consuming so much disk space. It could be that you have some data that would be better stored externally.
    Those that would benefit most from using a Time Capsule are those using portable computers, since these are the least convenient to connect directly to an external drive. Certainly, it doesn't make sense to have a portable connected directly to an external to allow hourly backups, which could occur easily when using a Time Capsule. And, I dare say that most portable computer users have internal drives smaller than 250 GBs. I know I certainly do.
    All this said, your question is really whether or not a Time Capsule is right for you. If you are filling a 250 GB hard drive, the 500 GB model would do, but just barely. Adding a second machine, also using all of a 250 GB hard drive, wouldn't be possible. In this case, even the 1 TB model would be just barely enough, if that. Again, you might want to consider your file management, or just stick with directly-connected external drives for use with Time Machine. There are scenarios where a Time Capsule makes sense, and scenarios where directly-connected solutions are better.

  • Time Machine Backup Is Too Large For Backup Disc NOT

    Hi, I have not been able to locate anything to help me with a time machine/time capsule issue I am experiencing. I have a 750 GB internal and a 1tb capsule. I have been using it to back up for well over a year with no real troubles. About three months ago, a message appeared that my time machine drive was basically filling up and that it was going to start deleting old backups to replace with new ones. No big deal I knew that this day would come. Well, today, I receive a message that it wants to back up 621.99 gbs (the entire drive!) and there is only 59.33 gbs of space. This should not be the case, it seems to think it is backing up a brand new initial back up for some reason when it shouldn't be. Why is it trying to back up the entire drive? I can't figure out what to do to get it back on track. This is the problem with my Apple products, problems are so few and far between for me that I don't remember what to do to correct the issues that arise every couple years. Can anyone guide me?

    ...have not been able to locate anything to help me with a time machine/time capsule issue I am experiencing.
    Nothing here, John?

  • Error: "This backup is too large for the backup volume."

    Well TM is acting up. I get an error that reads:
    "This backup is too large for the backup volume."
    Both the internal boot disk and the external baclup drive are 1TB. The internal one has a two partitions, the OSX one that is 900GBs and a 32GB NTFS one for Boot Camp.
    The external drive is a single OSX Extended part. that is 932GBs.
    Both the Time Machine disk, and the Boot Camp disk are excluded from the backup along with a "Crap" folder for temporary large files as well as the EyeTV temp folder.
    Time Machine says it needs 938GBs to backup only the OSX disk, which has 806GBs in use with the rest free. WTFFF? The TM pane says that "only" 782GBs are going to be backed up. Where did the 938GBs figure come from?
    This happened after moving a large folder (128GB in total) from the root of the OSX disk over to my Home Folder.
    I have reformated the Time Machine drive and have no backups at all of my data and it refuses to backup!!
    Why would it need 938GBs of space to backup if the disk has "only" 806 GBs in use??? Is there anyway to reset Time Machine completely???

    TM makes an initial "estimate" of how much space it needs, "including padding", that is often quite high. Why that is, and Just exactly what it means by "padding" are rather mysterious. But it does also need work space on any drive, including your TM drive.
    But beyond that, your TM disk really is too small for what you're backing-up. The general "rule of thumb" is it should be 2-3 times the size of what it's backing-up, but it really depends on how you use your Mac. If you frequently update lots of large files, even 3 times may not be enough. If you're a light user, you might get by with 1.5 times. But that's about the lower limit.
    Note that although it does skip a few system caches, work files, etc., by default it backs up everything else, and does not do any compression.
    All this is because TM is designed to manage it's backups and space for you. Once it's initial, full backup is done, it will by default then back-up any changes hourly. It only keeps those hourly backups for 24 hours, but converts the first of the day to a "daily" backup, which it keeps for a month. After a month, it converts one per week into a "weekly" backup that it will keep for as long as it has room
    What you're up against is, room for those 30 dailies and up to 24 hourlies.
    You might be able to get it to work, sort of, temporarily, by excluding something large, like your home folder, until that first full backup completes, then remove the exclusion for the next run. But pretty soon, it will begin to fail again, and you'll have to delete backups manually (from the TM interface, not via the Finder).
    Longer term, you need a bigger disk; or exclude some large items (back-them up to a portable external or even DVD/RWs first); or a different strategy.
    You might want to investigate CarbonCopyCloner, SuperDuper!, and other apps that can be used to make bootable "clones". Their advantage, beyond needing less room, is when your HD fails, you can immediately boot and run from the clone, rather than waiting to restore from TM to your repaired or replaced HD.
    Their disadvantages are, you don't have the previous versions of changed or deleted files, and because of the way they work, their "incremental" backups of changed items take much longer and far more CPU.
    Many of us use both a "clone" (I use CCC) and TM. On my small (roughly 30 gb) system, the difference is dramatic: I rarely notice TM's hourly backups -- they usually run under 30 seconds; CCC takes at least 15 minutes and most of my CPU.

  • "Backup is too large for the backup volume" error

    I've been backing up with TM for a while now, and finally it seems as though the hard drive is full, since I'm down to 4.2GB available of 114.4GB.
    Whenever TM tries to do a backup, it gives me the error "This backup is too large for the backup volume. The backup requires 10.8 GB but only 4.2GB are available. To select a larger volume, or make the backup smaller by excluding files, open System Preferences and choose Time Machine."
    I understand that I have those two options, but why can't TM just erase the oldest backup and use that free space to make the new backup? I know a 120GB drive is pretty small, but if I have to just keep accumulating backups infinitely, I'm afraid I'll end up with 10 years of backups and a 890-zettabyte drive taking up my garage. I'm hoping there's a more practical solution.

    John,
    Please review the following article as it might explain what you are encountering.
    *_“This Backup is Too Large for the Backup Volume”_*
    First, much depends on the size of your Mac’s internal hard disk, the quantity of data it contains, and the size of the hard disk designated for Time Machine backups. It is recommended that any hard disk designated for Time Machine backups be +at least+ twice as large as the hard disk it is backing up from. You see, the more space it has to grow, the greater the history it can preserve.
    *Disk Management*
    Time Machine is designed to use the space it is given as economically as possible. When backups reach the limit of expansion, Time Machine will begin to delete old backups to make way for newer data. The less space you provide for backups the sooner older data will be discarded. [http://docs.info.apple.com/article.html?path=Mac/10.5/en/15137.html]
    However, Time Machine will only delete what it considers “expired”. Within the Console Logs this process is referred to as “thinning”. It appears that many of these “expired” backups are deleted when hourly backups are consolidated into daily backups and daily backups are consolidated into weekly backups. This consolidation takes place once hourly backups reach 24 hours old and daily backups reach about 30 days old. Weekly backups will only be deleted, or ‘thinned’, once the backup drive nears full capacity.
    One thing seems for sure, though; If a new incremental backup happens to be larger than what Time Machine currently considers “expired” then you will get the message “This backup is too large for the backup volume.” In other words, Time Machine believes it would have to sacrifice to much to accommodate the latest incremental backup. This is probably why Time Machine always overestimates incremental backups by 2 to 10 times the actual size of the data currently being backed up. Within the Console logs this is referred to as “padding”. This is so that backup files never actually reach the physically limits of the backup disk itself.
    *Recovering Backup Space*
    If you have discovered that large unwanted files have been backed up, you can use the Time Machine “time travel” interface to recovered some of that space. Do NOT, however, delete files from a Time Machine backup disk by manually mounting the disk and dragging files to the trash. You can damage or destroy your original backups by this means.
    Additionally, deleting files you no longer wish to keep on your Mac does not immediately remove such files from Time Machine backups. Once data has been removed from your Macs' hard disk it will remain in backups for some time until Time Machine determines that it has "expired". That's one of its’ benefits - it retains data you may have unintentionally deleted. But eventually that data is expunged. If, however, you need to remove backed up files immediately, do this:
    Launch Time Machine from the Dock icon.
    Initially, you are presented with a window labeled “Today (Now)”. This window represents the state of your Mac as it exists now. +DO NOT+ delete or make changes to files while you see “Today (Now)” at the bottom of the screen. Otherwise, you will be deleting files that exist "today" - not yesterday or last week.
    Click on the window just behind “Today (Now)”. This represents the last successful backup and should display the date and time of this backup at the bottom of the screen.
    Now, navigate to where the unwanted file resides. If it has been some time since you deleted the file from your Mac, you may need to go farther back in time to see the unwanted file. In that case, use the time scale on the right to choose a date prior to when you actually deleted the file from your Mac.
    Highlight the file and click the Actions menu (Gear icon) from the toolbar.
    Select “Delete all backups of <this file>”.
    *Full Backup After Restore*
    If you are running out of disk space sooner than expected it may be that Time Machine is ignoring previous backups and is trying to perform another full backup of your system? This will happen if you have reinstalled the System Software (Mac OS), or replaced your computer with a new one, or hard significant repair work done on your exisitng Mac. Time Machine will perform a new full backup. This is normal. [http://support.apple.com/kb/TS1338]
    You have several options if Time Machine is unable to perform the new full backup:
    A. Delete the old backups, and let Time Machine begin a fresh.
    B. Attach another external hard disk and begin backups there, while keeping this current hard disk. After you are satisfied with the new backup set, you can later reformat the old hard disk and use it for other storage.
    C. Ctrl-Click the Time Machine Dock icon and select "Browse Other Time Machine disks...". Then select the old backup set. Navigate to files/folders you don't really need backups of and go up to the Action menu ("Gear" icon) and select "Delete all backups of this file." If you delete enough useless stuff, you may be able to free up enough space for the new backup to take place. However, this method is not assured as it may not free up enough "contiguous space" for the new backup to take place.
    *Outgrown Your Backup Disk?*
    On the other hand, your computers drive contents may very well have outgrown the capacity of the Time Machine backup disk. It may be time to purchase a larger capacity hard drive for Time Machine backups. Alternatively, you can begin using the Time Machine Preferences exclusion list to prevent Time Machine from backing up unneeded files/folders.
    Consider as well: Do you really need ALL that data on your primary hard disk? It sounds like you might need to Archive to a different hard disk anything that's is not of immediate importance. You see, Time Machine is not designed for archiving purposes, just as a backup of your local drive(s). In the event of disaster, it can get your system back to its' current state without having to reinstall everything. But if you need LONG TERM storage, then you need another drive that is removed from your normal everyday working environment.
    This KB article discusses this scenario with some suggestions including Archiving the old backups and starting fresh [http://docs.info.apple.com/article.html?path=Mac/10.5/en/15137.html]
    Let us know if this clarifies things.
    Cheers!

  • "This backup is too large for the backup volume" - Info

    Hi there. I had a problem with my time machine and got an error stating "This backup is too large for the backup volume". I did noticed after logging in that TM was indexing in the upper right corner [magnifier with a flashing dot(spotlight)] for a few seconds. So then I went on to "back up now" and it was preparing and then I got the Error message described above. So I uninstalled my anti-virus (you must disable auto protection/or exclude timemachine.app and its plist file (location below)from Anti-virus preferences in the case you have a anti-virus app, otherwise it will take forever to back up.) though that was not my issue. I then turn off time machine and deleted this .plist file in Macintosh HD > Library > Preferences > com.apple.TimeMachine.plist....STOP here if this fixed your problem after restarting. Time machine External Drive in Disk Utility **THESE STEPS WILL ERASE YOUR ENTIRE BACKUPS** ( "Erase" and rename or "partition" to make more that one partition on the External Drive if you wish, and Rename) (Disk utility> Partition tab> "option" you must - guid=intel / apple partition map=PowerPC)...sorry alot of newbie out there...by deleting the "com.apple.TimeMachine.plist" = when you plug in you TM it will ask you if you want to use the drive as a TM back up automatically. This did the trick. But to let you guys know I also used Cocktail (app) and used a feature it has to erase my computers spotlight index and rebuild it. Also in Cocktail, when you have your time machine plugged in you can erase its index and disable it all together. I recommend you first disable spotlight (before the first initial TM backup) in system preferences > spotlight> Privacy (tab) and plus to add time machine ...which has to be mounted (plugged in) to add from window under "Devices".

  • Time Machine Error - The backup is too large for the backup disk

    I have been using Lion (currently 10.7.1) on my MacBook Pro (13" - early 2011) since it was released.  I haven't had any serious problems with it.
    All of a sudden, I am getting an error in Time Machine.  When it tries to run a backup, the error "This backup is too large for the backup disk.  The backup requires 7.51 GB but only 630.1 GB are available."  What gives?  That's plenty of room.  I have installed Logic Studio and a few plug-ins, so the 7.51 GB is probably right.  The free space is correct as well.  I can't understand what the problem is.
    The backup disk is an external USB 2.0 drive with no other Time Machine backups on it or any other files.  The folder "Backups.backupdb" is the only thing on the root of the disk.
    I am reluctant to reset the Time Machine and lose all of the backups, but I will if anyone recommends it.

    Hi Linc,
    It is not working at the moment, as I have restored the original Lion image again; it has all my work and apps on it.
    Many thanks for the info on the log, though.  It tells a strange story.  Here's the log from the last backup that worked to the first one that failed: --

    I don't understand.  For starters, I think it's a little wasteful that 3.5 GB has been used to back up 601 KB.  That's the difference in free space on the backup volume between the two backups.  That can't be normal, surely.
    The only error is that mds[32] error, and from what I've read on forums, that seems to appear on backups that work perfectly.
    Too weird.  It looks like I'll have to reinstall Lion and all my applications again to get Time Machine working, or find another backup solution.

  • This backup is too large for the backup volume - ridiculous Size!!!

    Hi .. i own a macbook 13" aluminium, I have Snow Leopard 10.6.2 , and i change my internal hard drive to a 500Gb.
    I bought 1Tb Western Digital My Book USB External Drive to use it for back ups using Time machine.. at the beginning worked great, when i changed my hard drive i restore everything in lest than 2 hours.
    Then one time, it said that the hard drive where going out of space, and i said to delete the oldest backups, it erase everything and kept the last back up. Since then, it came a message
    *_+This backup is too large for the backup volume. The backup requires 2.73EB but only 995 Gb are available.*+_
    its ridiculous, when i go to the time machine preference, it said that the full size back up it would take 83Gb only.
    I tried everything, formatting the unit, taking out the partition , and making it out again, it makes the first full back up, but then the same message...
    Please anyone... i am desperate
    Thanks Again

    Hi, and welcome to the forums.
    That message seems to indicate that something is corrupted on your internal HD. Do a +*Verify Disk+* on it, per #A5 in the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.
    If that finds errors, you'll have to use the procedure in the yellow box there to Repair them.
    If that does not find errors, Restart your Mac and do a "full reset" of Time Machine, per #A4 there.
    I tried everything, formatting the unit, taking out the partition , and making it out again, it makes the first full back up, but then the same message...
    What partition? Are there multiple partitions on your TM drive? How large is the one for Time Machine? Check the setup per #C1 of the Troubleshooting Tip.

  • Time Machine Error This backup is too large for the backup disk

    Hi, I have a 1TB Time Capsule which backs up my Mac. I was having some issues with my mac so I decided to perform an erase and install and then use Migration Assistant to transfer everything back to my Mac.
    After I reinstalled Snow Leopard and restored my Mac using Migration Assistant, Time Machine says that the backup has failed. It says " Time Machine Error This backup is too large for the backup disk. The Backup requires 663 GB but only 255 GB are available.
    What do I do? Is my only option to erase my Time Capsule and have it back everything up from scratch?

    Hi, thanks for the help. I erased everything off of the Time Capsule and it's backing up my Mac from scratch. It's almost finished backing up my whole mac. It's now at 641.86gb of 646.54gb but it's now backing up very slowly. It's backing up .1 every few minutes. Is this normal?

  • This backup is too large for the backup volume - ridiculous backup size

    I have had big problems with Time Machine today. I have been successfully using it for 2 months now. I have about 30Gb spare on my iMac hard drive (out of 233Gb) and my Time Machine uses 195Gb out of 466Gb available.
    However, today I have lost all my Time Machine history except for one backup made this morning, and I am now getting an error message saying:
    "Time Machine Error
    This backup is too large for the backup volume. The backup requires 161061280.0 GB but only 270.4 GB are available.
    To select a larger volume, or make backup smaller by excluding files, open System Preferences and choose Time Machine"
    Clearly the required backup volume is wrong - that's 161,000.0TB!!!
    The same message has come up 3 times now.
    Can anyone help/advise on what to do next?

    Thanks Peggy,
    I re-indexed Spotlight and ran Time Machine again, but got exactly the same error message and the same massive storage required.
    I've opened Console as you suggested and these are a set of the messages from one back-up attempt yesterday (Console doesn' show anything earlier than 17.32 yesterday - but the problem started earlier than that I believe):

  • Time Machine Error.  Backup is too large for the backup disk.  Backup requires 289.28 GB but only 177.01 GB are available.

    My Mac has not been backing up for some time.  Tried Apple Support, but couldn't figure out problem.
    Receive the following error...
    Time Machine Error
    This backup is too large for the backup disk. The backup requires 289.28 GB but only 177.03 GB are available.

    See #C4 in Time Machine - Troubleshooting.
    If that doesn't clarify the situation, post back with:
    How much data is on your internal HD (and any others being backed-up)?
    How large is your Time Capsule?
    Is there anything else on the TC besides these backups?  If so, what and how large?

  • HT3275 Message: This backup is too large for the backup volume?

    Time Machine no longer backs up.  I keep getting this message (This backup is too large for the backup volume) though I have excluded and deleted a huge number of documents, photos, etc.  Help!  Help!

    Do you have the Warn when old backups are deleted box checked in Time Machine Preferences > Options?  If so, just remove the check and run another backup.  Then Time Machine will delete your oldest backup(s) to make room for the new one.
    If not, see #C4 in Time Machine - Troubleshooting, probably the pink box there.  If that doesn't clear it up, post back with the amount of data being backed-up (ie, how much is on your internal HD and any others being  backed-up), how large your backupd drive is, and whether there's anything else on it (if so, how much?).
    A screenprint of the message might help, too.

  • Problem: backup is too large for the backup volume

    I am seeing the following message. Any hints as to what is going on?
    The backup is too large for the backup volume. The backup requires 711.1 MB but only 20.2 GB are available.
    To select a larger volume, or make the backup smaller by excluding files, open System Preferences and choose Time Machine.

    I fixed it. I think.
    Recipe:
    1. Logged in an an administrator (usually my work accounts are Standard)
    2. Ran Onyx utility (http://www.apple.com/downloads/macosx/systemdiskutilities/onyx.html)
    3. Noted that under "Scripts", the weekly and monthly scripts had not been run since before the problem began
    4. Ran weekly and monthly scripts
    5. Restarted Time Machine
    6. TM now correctly deleted my old backups, freeing about 30GB. It now correctly reports that my oldest backup is Feb 3 2008, previously it said Dec 27 2007.
    7. TM ran perfectly
    So it appears that there was some bad juju in the old caches cleared by the scripts. If this pops up again, I will report it here.

  • Time Machine backs up one MacBook, but "backup is too large" for second

    We have two MacBooks running OS 10.5.8 and both are connected wirelessly to Time Capsule. My daughter's laptop backs up fine. But my wife's laptop fails. It backed up one time when I first installed it, but never since. The error message I get is that the backup is too large for the backup volume -- 71.8 GB required but only 7.4 GB available.
    My daughter's machine has a lot of photos and iTunes files on it, so it shows 141 out of 150 GBs are used up. The Time Capsule, which I understood to have 1 TB actually shows only 7.4 GB out of 463 GB are available.
    And actually, when I try to manually run Time Machine on my wife's machine I get the really long Preparing message, and then the Time Machine Error message about not enough volume.
    Should a machine with 150 GB capacity really be taking so much space on Time Capsule, and why the difference between the 1 TB advertised capacity and the <500GB of memory that actually appears to be there?
    Does any of this suggest I need to restore the external or internal drives?

    Does it make sense that it's trying to back up about 60 GB (Time Machine adds 20% for temporary workspace) from that Mac?
    If so, see if it has the +Warn when old backups are deleted+ box checked in Time Machine Preferences > Options.
    Click the Time Capsule in a Finder sidebar. If the Finder is in +Column View,+ you should see something like this:
    |
    except there should be two +sparse bundles+ listed in the third column. Right-click each one in turn, select +Get Info,+ and see what's shown for Size. Report back with the numbers. Also tell us if you have any other data on your TC, besides the 2 Mac's backups.

    That sounds like it's doing a "deep traversal," perhaps after a long time since the last backup, where it has to compare everything on the Mac to the backups, to figure out what needs to be backed-up.
    Should a machine with 150 GB capacity really be taking so much space on Time Capsule
    Sure. Time Machine will use up all the space available to it, then begin deleting the oldest backup(s) when it needs room for new ones.
    and why the difference between the 1 TB advertised capacity and the <500GB of memory that actually appears to be there?</div>
    It does sound like you have a 500 GB Time Capsule. The original ones were 500 GB; I'm not sure when the 1 TB version came out, and now you can get them with 2 TB. How old is it, and why do you think it's a 1 TB model?

  • Time Machine completes once, then says "too large for backup disk"

    Hello all,
    I'm a very experienced, certified Apple tech, with over 15 years' experience working on Macs, having used them since 1984.
    Client's iMac (27-inch, Late 2009)
    Mac OS X 10.6.8, fully up to date
    12 GB RAM
    History: Internal 1 TB hard drive was failing. Mac out of warranty, so HDD was replaced with a new 1 TB hard drive.
    Data was cloned from old drive using SuperDuper!
    Now, Time Machine will not back up more than once.
    The error reads:
    "Time Machine could not complete the backup.
    This backup is too large for the backup disk.
    The backup requires 728.32 GB but only 568.57 GB are available."
    The backup drive is 1.5x the size of the internal drive. There are no other hard drives attached that would be included in the backup.
    Internal hard drive: 1 TB
    Available: 392 GB
    Used 608 GB
    External backup drive 1.5 TB
    Available 568.57 GB
    Used 931.39 GB
    I have tried many steps from the pondini.org site and other blogs and internet forums, including this one.
    External hard drive has been reformatted/erased several times.
    We have disabled  indexing, deleted the Spotlight index, and re-enabled indexing.
    I can't determine why the Time Machine backup is 1.5 times the size of the data on the internal boot drive.
    This was never a problem before the internal hard drive was replaced, so I think it's related to that.
    I had the client install BackupLoupe. Her computer is not at our office, but I can get more info from her if needed.
    If there's something obvious I'm missing, let me know.
    Thanks in advance,
    Dave
