Time machine full backup after disk and disk permissions repair

my macbook would not boot so i inserted the snow leopard DVD and did a disk repair and disk permissions repair, after that it booted perfectly but when it went to do a backup it did a full backup of 149GB , i am unsure why it has done this and would like to know how to stop it as i am trying to save space on my time capsule.
thank you in advance

I'm afraid you don't have much choice. You do have lot of space available, though.
Node requires deep traversal:/ reason:must scan subdirs|new event db|
No pre-backup thinning needed: 165.92 GB requested (including padding), 507.60 GB available
The "deep traversal" means TM compared everything on your system to the backups, and estimates that about 138 GB is new/changed (it adds 20% for workspace on the TM disk - the "padding" in the message).
If there's about 138 GB on your system, see #D3 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), for some common reasons for TM to do a new full backup.
If there's more, #D4 there has some common reasons for large backups.
If all you did was repair disk and permissions, neither should have resulted.
the reason i did a permission repair and disk repair while running from the install disk was because my laptop would not boot from the internal disk so i did both just to be safe.
That's fine; just do the Permissions Repair again, while running normally.

Time Machine Full backup after disk move

I have followed the instructions for moving my Time Machine backup to a new disk as per instructions here. However, once I have completed the copy to the new disk, the first time that time machine runs, it seems to be do a full new backup and therefore there is not enough room on the new disk.
I get the following error: Time Machine could not complete the backup. This backup is too large for the backup disk.
Please help, this is driving me nuts.
Thanks,
Ian.

Peeps, I am so sorry, I am such an idiot, I have just realise what I have done wrong!!!
Whilst trying to build my new drive (part of which is to be my new Time Machine backup) I created a 500gb backup in my local Documents folder - this is why my initial Time Machine backup was so large, not because Time Machine was trying to do a full backup!!!
Thanks for looking,
Ian.

Restore Time Machine Full Backup After Catastrophic Failure

I am new to the Mac and using Time Machine as my primary backup utility. My concern is the way it creates one full backup at the beginning and only incremental ones after that. If the full backup gets overwritten due to the program needing hard drive space, does it know to create another full backup, even if it needs to delete some older incremental backups?
I am concerned I will need to complete a full restore at some point, and will not be able to do so because there will not be a full backup present on the Time Machine disk.
Also, who has had to restore from a catastrophic disk failure using an external time machine disk? Is this easy? Does it work properly?

you concerns are unfounded. due to the way TM keeps data organized every backup is full and independent of any other backups.
when TM makes a backup it only backs up afresh new and changed files. everything else is _*hard linked*_ to existing backup copies.
deleting an earlier backup to save space as TM does sometimes has zero effect on the remaining backups. they remain full and complete. doing a full system restore from TM is very easy. you boot from the SL install DVD and select "restore system from backup" from Utilities menu.
However, it should be noted that TM is still very buggy and doing a full restore can not be tested until you actually do it. therefore, it's advisable to have a double backup using a different backup tool. bootable clones are the best for doing a full restore. CCCloner and Superduper are excellent cloning backup programs.

How to save SOME time machine Mac backups from the TM disk to other disk WITHOUT formatting the destination disk?

Hi,
How to save SOME time machine Mac backups from the TM disk to other disk WITHOUT formatting the destination disk?
I have a Time Machine disk (A) including the backups of several different Macs (B, C, D & E) generated with an old Mac OS X 10.5.8 (iMac PowerPC) over the years.
I have transferred the old Mac contents to a new Mac with OS X 10.8.3 using Migration Assitant. All OK.
Now, I want to erase such TM disk A to use if for other purposes, but first, I would like to RECOVER the backups of some Macs inside it (D and E). Is that possible WITHOUT formatting the destination disk and selecting only some Macs from the TM disk and not the fulll TM disk? How?
Thanks.

Thanks for the reply. I do not think that is messy, anway. I simply used the same external disk as Time Machine disk for different Macs. And that worked OK all the time for years.
The ExternalTimeMachineDisk contains the folder Backups.backupdb
which contains the following folders (each one corresponding to the Time Machine backup made from each Mac):
Mac1
Mac2
MacBook1
MacBook2
In relation to my message above, is it possible to select specific files, folders or full Mac backups from such Time Machine disk and save them to other disk? How?
Thanks.

Access Time Machine partial backup after system restore

My iMac crashed. I ran Disk Utility Repair Disk on the hard drive and received this message: "Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files".
I had had Time Machine backing up regularly wirelessly, and previously hadn't noticed any problem with it. So I thought everything had been backed-up properly.
I reformatted the hard drive and chose to restore the system from Time Machine back-up. It turned out that you can only restore from full system back-ups and my Time Machine hadn't made a full back-up for half a year! Previously it had made full back-ups every 2 or 3 days then it stopped doing full back-ups half a year ago without any warning.
I went ahead with the system restore from the half-year-old full backup thinking that I would be able to access the partial back-ups once the system is restored. But I can't! If I access Time Machine, the most recent back-up I can see is the half-year-old full backup from which I restored the system. There are documents, music and hundreds of photos, originally saved to the hard drive since the last full back-up, that I cannot access, even though Time Machine had been backing up every day until the iMac crashed.
How can I retrieve these files from Time Machine?

Time Machine for backups for multiple Macs, disk space?

Hey there,
i have an Time Machine drive with backups of my old MacBook and a brand new MacBook Pro. Now i wanted to connect my new MacBook Pro with my Time Machine harddrive.
The Problem is this: First there were not enough disk space available on the harddrive, so i could not create a new backup of my MacBook Pro. Then i excluded some big folders and i could create my backup. My old Macbook is currently (and the next few month) not physically available at my place, so i could not delete old backups manually with this. But i want to keep this backups.
Now my question: In the future, will Time Machine delete my old MacBook backups or will it fail and my harddisk is full after 2 backups of the MacBook Pro?
Best regards and thanks
Johannes

Alright,
i have a few years of backups in this TM. I thought TM will delete old backups if the harddisk runs out of space, or am i wrong? The question is, if TM will delete old backups of other Macs synced with this TM.
Best regards
Johannes

Time Machine loses backups after a full restore.

Greetings
(Possibly due to parallels, my Imac was running so slow or hanging. As a result,) I ran a full system restore from Time Machine. It worked well. Then I thought I would try a better restore date and used that. After this successful restore, I now notice that all earlier backups have been deleted/lost - or at least they are not available on the Time Machine,
The only event in between was to add to the time machine a windows based account file.
Imac seems to run OK now, but files from around July to now are missing.

After a full restore, Time Machine may start a new backup. You can ctrl-click the TM icon and +Browse Other Time Machine Disks+ to view your old backups. I can't be sure, but you could try to go to TM Preferences and Change Disks to see if you can continue to back up to your old TM folder/sparsebundle. Otherwise, you will have 2 backups now, the old one being dormant, but accessible.

Using Time Machine to backup data FROM external disk to ANOTHER external

i have my itunes library and my iphoto library on an external WD disk connected to my MacBook Pro. So, i have a lot of nice data on that disk that i want protected... but Time Machine is not playing nice with the external hard drive. It's not listed on the list of items "Not to backup", yet when I go into the Time Machine interface, i can't go more than 1 level deep in Finder when selecting the external disk.
has anyone seen this behavior? it's supposed to work.
thanks!

Did you backup your data from that external disk using some other backup software before?
I am also trying to figure out problems with external HD using time machine to back it up. Am not quite sure yet why it is not working right.

Force Time Machine Full Backup

I wanted to update my Macbook Pro with a new Hard Disk, after preparing & installing the new HD and then chossing to restore from the Time Machine, i was surpised that the Time Machine showed me only some Backups(Full Backups), and the last full backup was 6 Months old, although i did a TM Backup just before installing the new HD, but apprently it is an incremntal backup, therfore it was not shown in the list.
So my question is how to force a TM Full Backup so that i can just restore it on the new HD. I know i can do it if i deleted all the old Backups, but i want to keep them, is it possible?

Time Machine full backup started... why!?

Installed Mavericks, played around a bit, time machine was behaving normally until today.
I thought the usual backup was starting, not so many changes since last one, maybe a couple of giga of new photos to add but Time Machine decided instead to delete the whole content and start from scratch.
My time machine disk is 1.5TB my full backup will be under 1.20TB, and again Mavericks was already backing up normally since I installed that... so what caused this absurd behaviour?
If this is not a bug, what else? Because of this at the moment I have no backup, time machine is working and if I am lucky it'll take one full day or two to have a backup again.

Time Machine keeps copies of everything currently on your Mac, plus copies of things you've changed or deleted. It varies widely depending on how you use your Mac, but Time Machine generally needs 2-3 times the space of the data it's backing-up, to be able to keep a reasonable "depth" of backups for you.
Is there some settings i need to change or is something wrong?
Probably neither.
If both Macs are running Snow Leopard, you may be getting notices like the one in the blue box in #C4 of Time Machine - Troubleshooting. You can stop those notices if you want.
If either is on Leopard, it's a different story. When Time Machine on a Mac running Leopard runs out of room, and the +Warn when old backups are deleted+ option is checked, it fails with a message like the one in the tan box in #C4. Remove the check from the box, and it will start deleting old backups.
But if you're getting the message in the pink box, something is likely wrong. See the suggestions and explanations there.

Time Machine First Backup After Upgrade Stuck @ Deleting Old Backups

This has been going on for the past 4 hours. Should I quit and start over. I think I may have messed it up when I clicked the "Encypt Disk" during the first update... Thanks...

Quite possibly.
I don't know how long it takes to encrypt about 480 GBs, but it will clearly take quite a while.
See #31 in Time Machine - Frequently Asked Questions for some info on encrypting your backups.
Use the widget in #A1 of Time Machine - Troubleshooting to display the backup messages from your logs. Locate the backup in question, then copy and post all the messages here.

Configuring Time Machine to backup certain folders and files.

Can it be done? I have 3 externals and don't want it to back up one of them. I removed it from the backup list but it still continues to backup that particular drive. Also wondering if I could configure Time Machine to not backup certain folders. I felt like when I first set up Time Machine, I was able to do this.
Thanks everyone.

Hello Warren:
That should be available to you in system preferences>Time Machine>options.

Time machine full backup

Why does my computer start a new backup series every week / 10 days now? Never used to with Lion.

It backs up every hour which is OK but the frequency of starting a new backup has increased dramatically since I switched to Mountain Lion.
It now wants to start a new backup every week to 10 days and it takes forever to do a new full backup.

Unable to boot after Time Machine full system restore!!

I was having some serious slowdowns with my computer. I did multiple RAM and HD hardware tests, everything seemed to be working fine. I had recently deleted a bunch of files in order to free up some HD space, so I thought that may be the culprit. So I did a Time Machine backup and restored the Powerbook to it's original 10.3 software. All was fine. Then I upgraded back to 10.5 and all was fine. Then I did a Time Machine full system restore overnight and got the message "Your restore was successful, you must now restart your computer" (or something to that effect). Now I get the start-up chime and startup screen (apple logo) but then the computer shuts itself down. I have reset the PMU and PRAM to no effect. I have tried booting up in safe made, also no dice. I have tried starting it up with the time machine HD attached - doesn't help. I guess I'll need to hit the genius bar but wanted to ask the friendly discussion forum folks first. thanks in advance.

Hi coldengray
Did you try to start from your System-CD? Hold down C-key during startup, start DiskUtility from the menu and verify/repair disk and permissions there.
If the CD is not available you can also connect your TimeMachine-Disk, select it as startup volume in System Preferences/StartupDisk, restart and then run DiskUtility from folder Applications/Utilities
Good luck P

FYI: No Sleep during Time Machine initial backup

Just an FYI - I noticed that during the first Time Machine full backup, the computer does not go to sleep.
I would also assume that if you computer is asleep, it will not wake for each hourly backup.

Hi, and welcome to the forums.
You need to know that backing-up that way is "iffy" and +*not supported by Apple.+* See Using Time Machine with an Airport Extreme Air Disk (or use the link in *User Tips* at the top of this forum).
Kernel panics are usually caused by hardware problems, but can be software.
Disconnect all peripherals, except keyboard and mouse. Reconnect one at a time to see if you can find the culprit.
If that's no help, run the Apple Hardware Test: http://support.apple.com/kb/HT1509
And perhaps a heavy-duty memory test, such as the free Rember: http://www.kelleycomputing.com/

If you still want to back up via the Airport, the first backup will be much faster if you connect via Ethernet.
