Reinstalling OSX: Will Time Machine read previous backup through interface?

Or will I only see backup through Finder?

Provided you are simply reinstalling Leopard on the same hardware and nothing else is changing (particularly your computer name in the sharing preference pane), Time Machine should be unaffected.

I need to reinstall OS X, will Time Machine recognise my backup drive?

Due to permissions problems I need to reinstall my OS. Will my backup drive still be recognised by my MacBook Pro after a fresh install? Also will the permissions problems simply still be there if I restore using Time Machine?

Not necessary. Use Disk Utility in your Applications/Utilities folder.
The reason I checked permissions in the first place was because a program was not opening (Limewire). The dock icon would bounce once then nothing.
You need to find out why that is. Reinstalling your entire OS is vast overkill, and probably won't help anyway. The simplest solution might be to re-download and reinstall it. If that doesn't help, your best bet might be to first search for Limewire in the +Using Leopard+ forum to see if anybody else has had the same problem. If not, post it there, with as much detail as you can.
Anti virus software shows no viruses
There are no Mac viruses. None. Most Mac users don't run any anti-virus software. Most of the anti-virus software, especially the stuff you pay for, is worse than a virus!
Some folks do run it, to keep from passing Windoze viruses they might get on to their PC friends. The free ClamXav is most often recommended here by those who know about such things, and they say it's the least obnoxious. Do a search for virus in the +Using Leopard+ forum, and read some of the many threads.

After reinstalling 10.6 Time Machine deleting ALL backups - Help!

I recently reinstalled Snow Leopard. I then re-enabled Time Machine and let it run for a while. Then I discovered to my dismay that it had deleted several months of backups, and it looked like it was going to delete them all. So I turned it off.
Does anyone know why it is doing this? I have done reinstalls before and TM has picked up seamlessly from where it left off. But not this time.
A thought: I deleted the entire Caches folder from my Library - could that made TM think it needs to start from scratch with a brand new backup?
Any help would be greatly appreciated.

It may depend on exactly what you did. If you just installed a fresh version of OSX "over" the old one, Time Machine should only back up the new version of OSX.
If you erased the HD first, then installed OSX and used Setup Assistant to transfer everything else from your backups, it shouldn't have done a full backup. Sometimes, however, it does anyway.
If you erased, installed OSX, and used any other method to put your data back, yes, Time Machine will do a new, full backup. You can't prevent it on Snow Leopard. (There is a way on Lion).
If you really need the old backups, your only option is to let Time Machine start fresh on a different drive. You can always see and restore from the old one via the Browse... option, per #17 in Time Machine - Frequently Asked Questions.
A thought: I deleted the entire Caches folder from my Library - could that made TM think it needs to start from scratch with a brand new backup?
No. That folder is automatically excluded from backups.

I upgraded to Yosemite and new Numbers. Can not use my spreadsheet and can not find it. How do I retrieve from time machine a previous backup?

I just upgraded to Yosemite on a MacBook Pro and also needed to upgrade Numbers. However, I can not get a spreadsheet that I had prior to this. I did backup to time machine. How do I now restore to get that spreadsheet?

Open the folder you thought it was in and Enter Time Machine. Go back in time until your find it.
You can also use the search field in the Finder window in Time Machine to search for the file.

Will time machine do a full backup of external volume (extra storage) after new logic board?

I have a MacBook Pro running leopard, that just had the logic board replaced. I haven't picked it up yet, but I am told that my hard drive and data were not touched.
I have read Pondini's very helpfull info/site, so I know that time machine will want to start a new set of backups.
Here is my question, based on my setup: in addition to the internal HD, I have a firewire drive for additional storage of files. Time machine backs up both volumes to another, larger, FireWire drive
Now, after the new logic board, will time machine make a whole new copy of the external storage drive as well as the internal? Or just the internal?
Basically, I know time machine will think it's on a new machine, but will it treat the external storage as if it were new as well?
I would appreciate any help or advice you can give me. Thanks.

Still no answer? I do have the same trouble on my iMac G5 PPC with 10.5.8: I just replaced the MOB and Time Machine insists to create a new bkup! Attempted with "tmutil" command but doesn't work on my OS...it is really impossible to tell the machine to learn the new address? I DON'T want to believe it!
Tks for any help

Due to NAS issues, when I started a new time machine backup it did not have the old backups available. My question is do I need to delete them or will time machine automatically reclaim the space? Only one Sparse Bundle, same name.

Due to NAS issues, when I started a new time machine backup it did not have the old backups available. My question is do I need to delete them or will time machine automatically reclaim the space? There is only one sparse bundle but when I enter time machine I don't see my historic backups. I use a synology DS212 for my time machine. Started a new backup which is 218gb but it says 618 gb is occupied therefore it looks like 2 or 3 backups are still on the disk. Before my NAS issues the last backup was in 2014. As you can see there is a second sparse bundle from 2012. Not sure what that is.

This is an old message now, but what happened to me similarly was:
I had a major computer crash and through complicated pathways ended up reinstalling (Mavericks) as a new user (long story).
At least I had good Time Machine backups on an NAS drive (Synology DS212j), or so I thought - when I started Time Machine up again, the old backup file was gone, replaced by a new one using my "new computer" name. The old file was gone both by directly mounting the NAS drive and by clicking "Enter Time Machine".
It's like I had {OldShareName}.sparsebundle and then it was replaced by {NewShareName}.sparsebundle, all of the old info vanished.
(I have spent a week finding old files elsewhere and have completed a satisfactory self-restore. It pays to "archive" [my own variation of] as well as "back-up".)
My belief is that if this were a wired-netword-drive, e.g. plugged right into my iMac with a USB cable, then the old file would have remained.
But this is an NAS drive, connected directly to my Airport wireless router, and I don't know the significance of the fact that it stores its Time Machine backups as "sparsebundle" files rather than simply as plain(er) files.
As usual when things get complicated with computers (not just Apple computers) there was never a warning message. Something like "YOU'RE ABOUT TO DELETE A TIME MACHINE BACK-UP FILE!!!" would have made my life a lot simpler.
BTW, I did try a "restore from Time Machine" option the first thing I had my "new computer" (old hardware, 2009 iMac) up and running, using Migration Assistant, and it ran for many hours and then failed in the wee hours - what that has to do with anything I'm not sure.
I'm not sure that I have a question about this other than "why do these things happen to me?", but it's a warning. Apart from that I've been very happy with the stability and reliability (but not the cost or set-up complexity) of NAS vs. directly-cabled external drives.

"Time Machine Error The backup volume is read only"

Lately, every time I try to backup to my Time Capsule using Time Machine it fails and I get a message saying "Time Machine Error The backup volume is read only. To select a different volume, open system preferences and choose Time Machine" So I do that and I see the Time capsule listed. I don't want to select anything but the Time Capsule, cuz what else do I have, right? Am I wrong in assuming the "backup volume" is the Time Capsule? Anyway, I have tried changing the permissions on the time capsule, but when I get the "get info" box for the time capsule, there is not an option to change those settings, they are grayed out. Every thing worked well for about a week and then this started. My backup volume must have been "Read & Write" at first, because I can see what was backed up when I open Time Machine. Anybody have a clue what's going on? How can I make the back up volume "Read & Write" again and why did it change to "Read Only?"

Nope, I am using the same passwords as ever, both users have the same password, BTW. The password I gave to the Time Capsule is different, tho, but that password is for the wireless aspect of the Time Capsule, so that wouldn't have anything to do with it, would it?
I also get a message box that says "Disk Repair The disk "Backup of XXX's Computer" was not repairable by this computer, it is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible." This box appears in conjunction with the appearance of the Norton's virus scan box scanning the time capsule.

Will Time Machine backup iTunes while it is open?

Hey guys! Quick question:
I recently learned that Time Machine does not backup any changes made in iPhoto while it is open. It needs to be closed in order for it to backup the changes made. Does the same apply for iTunes?

Issue was active scanning in VirusBarrier X5. I just excluded the Time Machine Drive from scanning and the issue was resolved. Can see discussion in this thread:

Doesn't Time Machine delete old backups when it needs more space?

I've had time machine running for a long time now. It worked flawlessly for quite some time.
Today it gave me the error that there was not enough free space on the disk to complete the backup (the error message says something like there is 360 GB of data on the Time Machine drive already, 140 GB of free space and it would require more than that to complete my backup). I have a 500 GB Time Machine disk and my Mac has a 500 GB hard drive, so I should technically never run out of space.
The Time Machine almost acts like this is the first time I've ever backed up, which is not true. Shouldn't Time Machine delete old backups to make space for the new? What's even weirder is that if I open the "Star Wars" window of Time Machine I only see one backup from March 31, 2011, but I have been running Time Machine for well over a year now. I'm totally confused as to what happened. Any advice on how to get my Time Machine back up and running (without buying a new drive) would help!

You see only one backup in the Time Machine window because Time Machine has deleted the older backups to make space to do the current backup.
Time machine needs some working space to do its backups, and so backing up a 500GB drive onto a 500GB time machine volume is not ideal.
However, I do essentially the same thing, and what I do, when I have this problem, is exclude things from the backup.
First off, figure out what you changed. If you moved things from one partition to another, then that will cause a backup of the size of the thing that was moved. This may be why you have a large backup.
When I have this problem, I exclude large things that have changed recently from the backup. This makes the backup smaller, and means that there is less working space needed. I do this until I get a successful backup. Then I remove things, one by one, from the exclusion list, and back up after each one.
So, for instance if you just put 4 new folders on your drive, each of which s 20GB of data and they are named A, B, C and D, add all four to the exclusion list, do a backup, then remove A from the exclusion list (leaving B, C & D on it) and do a backup, and continue like this, adding 20GB of backup data each time until none of the new data is on the exclusion list and you get a completed backup.
Another possible issue, if you use multiple partitions, is that Time Machine may be keeping an obsolete backup of a partition that you previously reformatted. To see if this is the case, go into time machine (The universe interface) and go back to the most recent backup it shows. Click on your computer and see what partitions show up-- are any of them old ones that have been reformatted and renamed? You may be storing a duplicate backup because Time Machine does not realize that the disk that went away isn't coming back (because it has been reformatted as a different partition)
You can right-click on these items and remove them from your backup by sleecting "Delete all backups of...." This will free up space as well.

Time Machine: "Partially Deleted Backup"

Last night, after Time Machine performed a backup and began its post-backup thinning, it got stalled on "Finishing backup... ." The system log showed that it was attempting to delete a previously partially deleted backup:
Starting standard backup
Starting post-backup thinning
Found partially deleted backup - trying again to delete: 2009-09-30-110803
The backup it was trying to delete was the last one on its list (i.e., the oldest one on that TM volume). And when I opened it up, it indeed appeared to be a partially deleted folder. So I let TM run. However, it never finished "Finishing backup... ," so after letting it run all night and all day, I simply told TM to stop. It did, and the system then added two more messages to the log, acknowledging my cancelation as well as TM's current success:
Starting standard backup
Starting post-backup thinning
Found partially deleted backup - trying again to delete: 2009-09-30-110803
Backup deletion was canceled by user
Backup completed successfully.
However, the next time TM ran, it began all over again:
Starting standard backup
Starting post-backup thinning
Found partially deleted backup - trying again to delete: 2009-09-30-110803
It's still sitting there in its "Finishing backup..." mode.
I was thinking about entering Time Machine, selecting that backup, and telling Time Machine to delete that backup—and only that backup. But I'm (a) not sure that will address the actual problem, and (b) wondering if deleting that particular backup (i.e., the oldest one on the list) is advisable.
Suggestions?

TM finding partially deleted backups, trying repeatedly to deleted them, and failing to.
(And yes, I though you meant that you'd tried to delete the backup yourself.)
It took forever. I ran TechTool Pro, and it "choked" (i.e., ran out of memory) trying to rebuild the directory. When I asked Disk Warrior to graph the directory, it revealed that it was more than 40% fragmented!
I'm not sure fragmentation is a problem, or even applies, given the structure of TM backups.
So I ran Disk Warrior. It ran without incident. When I then looked inside the TM drive, I discovered that along with rebuilding the directory—which is what I understood its job to be—DW apparently removed/deleted the offending (partially deleted) backup. The next time Time Machine ran, everything went smoothly. It's been running fine ever since.
Great! And yes, there are times it can repair/rebuild TM backups that nothing else can (I guess that's why it costs $100!).
I'm obviously quite pleased with the results: Not only did DW perform an incredible directory rebuild (fragmentation went from more than 40% to less than 1% !!) but it cleared out the partially deleted backup that was causing TM to stumble. But I remain awfully curious: Had I simply gone into Time Machine and deleted the partially deleted backup myself, wouldn't that have fixed the problem? (Granted, DW not only got TM back on track, but it also rebuilt its directory, which is a definite plus in my mind...I'm just trying to understand.)
It's possible you couldn't have deleted it completely, any more than TM was able to. Remember, a single backup folder has hard links to hundreds, thousands, or hundreds of thousands of other items. Just one of those being screwy can have a ripple effect through the whole structure.
And if you could have, it might well have left some of the actual backup files "abandoned" -- some or all of the hard links to them deleted, but still somewhere in the disk directory, so still taking up space.
I got the idea from
http://www.macosxhints.com/article.php?story=20090515063602219
which provided a link to the "solution" when partial backups remain that result in TM "error: 11" failures:
http://www.bytebot.net/blog/archives/2008/08/13/fixing-time-machine-backup-faile d-with-error-11
Admittedly, mine wasn't an "error: 11" problem, but it sure seemed similar. My hesitation/concern was due to the fact that the partially deleted backup was the last one (i.e., the "oldest") in my TM volume: I wasn't sure if deleting it would screw up all of the links used by the remaining backups. However, since DW removed it without causing any problems, it seems like I may have been able to accomplish the same result by removing it "manually" from within TM. If that is the case, then it suggests that there may not have been any actual "corruption."
Again, I am very happy with the result, and likely will resort to DW again the next time I have similar problems. The only reason I'm harping on it is simply to try to gain a deeper understanding of how to determine when such problems are indeed due to corruption as opposed to simply an errant file that causes TM to stumble. (Had TM indicated that it stumbled and was unable to successfully perform the backup, then I would have little doubt that there was actual corruption.)
