Why does Time machine not delete old backups

I dont understand Why time machine is not deleting old backups. As it worked first time with the same size backup drive as the drive its backing up, I assumed it would just delete the old backup as needed. Do I need a bigger backup drive?

I just want it to delete the old backup & replace it so i just have a copy. I guess i could just re format the drive each time but that just seems a waste of my time when TM should do this for me!
If this is all you want to do, turn off Time Machine, download SuperDuper! and use it for free. This will clone whatever drive you want and the free trial will erase your back up drive each time. I can't remember if it will let you choose what to back up or if it wants the entire drive. Also, I'm not sure if the Scheduler works with the free trial. Below are some verbiage for SuperDuper!. Looks like if you want Scheduling you will have to purchase a license.

Time Machine will keep making back ups and when it determines it needs space, it will delete older back ups. But it doesn't delete older ones each time it backs up.

Backup disk is full ... Time Machine not deleting old backups

In my Time Machine preferences it says "The older backups are deleted when your disk becomes full." Well ... my disk is full but Time Machine is not deleting its old backups to make more room.
So now TM is failing to backup.
Any suggestions for freeing up some disk space and getting back to getting backed up?
Thanks.

What message does it send? See #C2 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).
It will show you how to locate the message(s) that describe the problem, then help you fix it. If that doesn't help, post back with details, including all the messages, your setup (especially the destination for the backups), what you've done, and the results.

Do you have other data on the disk, in the same partition? If so, that's not a good idea, and may be the source of the problem. See #3 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).

OS X 10.7 Time Machine not deleting old backups to make space

after upgrading to 10.7, Time Machine no longer deletes old (over a year old) backups to make space when needed. Drive now full. Cannot manually delete and Time Machine does not seem to have a function to perform a deletion.

See C18 in the first linked article. Also, your backup drive should be 2-4 times your hard drive capacity.

Time machine not deleting old backups...

I am on Mavericks 10.9.1 and get the following error:
"The backup disk needs48.93 GB for the backup but only 30.99 are available. Select a larger backup disk or make the backup smalled by excluding files."
I recently had to unplug my external HD which I use for time machine back-ups, this error started when I plugged it back in just a few days ago. I have exlcuded some files from the back up and still get the error. My internal HD has 475.62GB of data on it, and I am trying to back up to a 500GB external HD, the total size of my backup is roughly 465GB.
Seems like I should have enough space for a back-up and TM should delete the old back-ups. I have been through a search of the forum and online and have not found a solution. Has anyone ran into this?
Thanks for the help!

I believe I was told that If you had older backups like ML and your disk is getting full it will not delete these because you are now backing up a new OS (Mavericks). It only deletes older backups of the same OS you are now using.

Time machine not deleting old backups of recovery partition

I have a Mac Mini running Lion Server. I have an external disk partitioned with a space for network backups and a smaller partition for backing up the server itself. The server has a 160GB disk, it is only using 29.27GB, the partition for backing up the server is 152GB (it's what was left over after creating the partition for the network backups). I figured since I'm only using about 30GB, 152GB should be plenty of space. However after 3 months of use I get the error "the backup is too large for the backup disk". In the past I have formatted the partition and restarted the backups, however it always fills up after 3 months. This time I decided to dig into it a bit more. I looked to see what was available in my backup, it only has one previous restore point. I browsed the disk and opened the backups.backupdb folder, checked the size of the folder with the computer name, it is only 9.44GB. I was wondering where all of the space went so I enabled hidden files, I found the .RecoverySets folder and found it was taking up 141.95GB. I looked at the recovery sets, there are 295 copies of com.apple.recovery.boot which all seem to contain the following files:
.disk_label                         749b
BaseSystem.chunklist       2KB
BaseSystem.dmg              454.6MB
boot.efi                              864KB
com.apple.Boot.plist          431b
kernelcache                       24.1MB
PlatformSupport.plist         2KB
SystemVersion.plist           478b
Of those files, the only file not dated Aug 11, Oct 6 or 12, 2011 is com.apple.Boot.plist which has a date that corresponds to when the backup was performed. These backups go all the way back to Jan 30, the last time I formatted the partition, but the user data backups only go back to the 27th and it hasn't been able to complete a backup since.
I thought Time Machine was supposed to only backup data that had changed since the last backup, and delete old revisions when space is running low, it seems that it is copying more than just the data that changed since the last backup and only deleting old revisions of user data, not system data. Is there a way to fix this permanently?

Time Machine is Deleting Old backups

Disconnected my MacBook Pro from its hard drives for two days. Re-connected, and ran Time Machine. It backuped up as normal. I walked away, seeing "49.8GB free of 499GB" on that external hard drive. I come back and Time Machine is "Deleting Old Backups ... " - and now 135GB free, and still deleting.
I realize that TM auto-deletes ... but does this sound "normal" to start its own deletions when there was 49GB remaining on a 500GB drive?
It's still deleting ...
Clint Bradford

If I said I connnected two disks, I apologize. One 500GB external hard drive is dedicated to just being a Time Machine backup for my 17" MacBook Pro.
Not sure what has happened ... but Time Machine cleared up space, and is now performing a 110GB backup ... kinda like it doesn't know it's the same computer attached to it.
This is NOT a critical problem ... I have full backup elsewhere. Just a little weirdness today ...

HT3275 Time Machine not deleting oldest backups when the disk is full

Time Machine not deleting oldest backups when the disk is full

Unfortunately, when this happens, Time Machine cannot erase enough space to create room for the new backup. Your options now are:
1) Add a new Time Capsule or a hard drive to the USB port on the existing Time Capsule and continue with backups
2) Manually delete backups from Time Machine....which is a long and tedious process. After a few hours, not much space will be reclaimed and it will not be long before the Time Capsule is full again
3) Erase the Time Capsule....if you really do not need all the old backups from months ago....and start over with a new Time Machine backup and move forward again

Time machine not deleting oldest backup on full network drive

Hi All,
I backup my iMac over the network to a share on a mac Mini. After around three months, the share is full. I expected Time Machine to just start deleting old backups, but it is not.
Time Machine gives me the following error:
"This backup is too large for the backup volume".
This is correct, but i thought Time Machine should have just deleted the oldest backup in this instance? Or does this not work when backing up over the network?
Thanks in advance for help and advice.
Cheers,

I have the exact same problem, but I am not using TM over a network... Only my local Mac Pro w/ a 600gb external drive. I recall back when I first got Leopard that time machine did in fact ask me if I wanted it to delete old backups after the drive filled up. Then one day it randomly decided to not delete old backups anymore... Instead displaying the same error message you get.
Can anyone help? (Besides telling me not to back up certain files, and to do it less often. Those are BS solutions! I want my entire HD backed up every time automatically erasing old backups when necessary. Is that too much to ask for?)

Time Machine incorrectly deleting old backups

Hi
I have a Macbook Air with a 128Gb SSD and I am using Time Machine to back up to an external 500Gb USB2.0 drive connected to my Airport Extreme.
The drive is formatted as Mac OS extended Journaled and is dedicated to Time Machine backups only. The problem is that Time Machine reports that the disk has run out of space and has deleted old backups. This can't be true as the Sparsebundle file is only about 70Gb and the drive has over 400Gb of capacity.
I have tried reformatting the disk and starting over but the problem keeps returning. When I enter time machine it has deleted all the old back ups and I can only go back in time a few days.
Any help appreciated!

Thanks for the reponse.
I checked and there are no other sparsebundles on the drive and there have been no changes made to the hardware.
Time machine seems to be working correctly as it successfully makes and completes teh back ups at regular intervals throughout the day. The message that there is no space available comes around every couple of weeks, which I'm guessing is based on the fact it keeps deleting all the recent backups except the last one and then the cycle repeats.
My own 'limited' opinion is that TM is having difficulty resizing the sparsebundle in some way and therefore can only maintain the backup within the initial size of the first backup. (e.g. the Macbook AIR SSD reports approx 113Gb of space and I am currently using 82.07Gb. The sparsebundle is currently sized at 75.66Gb on Disk (81.16Gb)
I checked the permissions of the sparse file and they are set to R&W for everyone so there shouldn't be an access problem.
I have only recently moved to the Mac environment and the Macbook air is my first apple computer so I am not very familiar with the environment, but this is an extremely annoying problem and renders TM vitually useless.

Time capsule not deleting old backups

My time capsule is no longer backing up due to lack of space. How can I get it to delete old backsups?

If you upgrade installed the OS, Mavericks.. then the TM seems to lose the ability to delete old backups..
Step in and do in manually.

Time Capsule not deleting old backups when full

I have a number of drives attached for alternating backups through Time Machine. When a generic USB drive I have gets full, it sends out a message saying that it will have to delete the oldest BU, which is fine by me. My relatively new tall Time Capsule just tells me to reduce the number of files I'm backing up or get another drive.
Also, form the numbers in the screenshot, it looks like it's trying to do a complete backup of my iMac drive when it should just be incremental, as it has been doing all along. Using 10.10.1 on a 2-year old iMac.
Any ideas why? Thanks to all in advance.

Incremetnal backups are small, so Time Machine usually does not have any trouble deleting a few of oldest incremental backups to make room for new small incremental backups.....but....450 GB is not an incremental backup, and Time Machine will not be able to delete enough data to make room for the large backup that it is being asked to complete.
If you want to keep all of the data on the current Time Capsule, you can add another USB drive to the Time Capsule, or another Time Capsule for that matter and continue backups that way.
Another option....the least expensive.....would be to erase the current Time Capsule drive and start over again with a new backup set.

Why does Time Machine not work over wifi but only via ethernet cable ?

Hi everyone,
It's been some time I have this problem now.
The first time I backed up my mac within Time Capsule with time machine, I chose to use the ethernet cable because the gigabit connection is much faster than the wifi for the first back up, but now, any time I want to update this back up, I need to connect the cable, cause "Time Machine can not connect to the Drive I picked" over wifi.
This is so annoying. Does anyone have a similar issue ?
Any solution ?
When I got this "error" I can use Utility Airport and get full access to the drive, even in finder. The only thing that doesn't work is TimeMachine connecting to the drive, even if it is detected by TimeMachine itself.
Thanks.

Typical Yosemite.
I suggest a full reconfigure of the TC.
Follow this list..
No files are deleted on the TC doing this although you might have to repoint your laptop to the backup.
Note.. even if TM does connect it will say it is going to do a new backup.. it is only when it starts that it discovers the backup exists and increments it.
Start from a factory reset. No files are lost on the hard disk doing this.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.

Time Machine not deleting old back ups?

I keep getting the error
"This backup is too large for the backup volume. The backup requires...."
I use the same 500GB volume for backups all day, every day. I thought the program was supposed to automatically delete old back ups to make room? I do not see any additional settings to confirm this but if you manually delete back up files, it really kind of screws things up. I see back ups that are 4-6 weeks old on the back up volume so there are plenty it could delete. Has anyone else seen this and how do you resolve this problem?
TIA

Do you mean via the Finder? If so, yes, it does.
If you have deleted any this way, do the following:
1. Turn TM Off.
2. Use Disk Utility (in your Applications/Utilities folder) to do a +Repair Disk+ (not permissions) on your TM drive. If it finds errors that it can't fix, try again until it does or you get the exact same results. If they can't be fixed, stop here and post back with the results.
Download the +Time Machine Buddy+ widget from: http://www.apple.com/downloads/dashboard/status/timemachinebuddy.html. It shows the messages from your logs for one TM backup run at a time, in a small window. Copy and post the messages here (be sure to get them all, as sometimes they overflow the small window).
Also, is there other data on your TM drive? If so, is it in the same partition as TM's backups?

Time Machine not deleting oldest backups?! Disc full.

What is wrong with Time Machine in Yosemite?
For years I have been using it and when the backup drive gets close to full I will be warned that the oldest backups will be removed to make space for the new ones.
It even says in System Preferences. "The oldest backups are deleted when your disk becomes full"
Why then does this not appear to work anymore? My Time Machine drive has become full and it REFUSES to back up now!
What must I do? Erase the whole drive and start again? Any answers appreciated.

Time Machine Not Recognizing Old Backups after getting hard drive replaced

Hello! I have a 13' Black Macbook pro which had a faulty hard drive so I had it replaced. Ever since then, all my old backups in Time Machine have been grayed out. I have no idea how to fix this and have tried almost everything on the web.
The only folder that allows me to "go back in time" is my Macintosh HD folder which I know I can access everything but it's a huge nuisance to not be able to click on a folder and go back in time in the same folder.
I just want things the way they used to be! Thanks for the help!

Hi, and welcome to the forums.
The problem is, you have a different HD. Even if it has the same name and contents as the old one, it's still a different HD, and Time Machine treats it as a different one.
There's no way to fool it into thinking it's not.
Technically, it has a different UUID (Universally Unique IDentifier); that's what OSX uses to keep track of drives, not their names.
As you do new backups, you'll be able to access them just as you did with the old drive.
