[OS X] Time Machine Error

 
Click for full size
Hi:

I have 2 3TB Time Capsules gigabit connected and one Seagate 3TB Hard disk Thunderbolt connected for TM backups. I have a second identical Seagate drive which I swap out each month and store off-site. This has been working well for me for 3 months now. Today I received the following TM error:

Files can’t be copied onto the backup disk because it appears to be read-only.

Latest successful backup: Yesterday, 5:48 PM

As seen below, I can read and write to the volume via terminal OK.


Disk Utility finds no problem with the device.

Any ideas?

If the drive is connected directly to the computer via USB try and see if the ignore ownership is turned on. Having that turned on will usually resolve that issue. Otherwise I would try repairing permissions on the drive.

Also, FYI, just because you have write access to the root folder doesn't necessarily mean you have access to the necessary subfolder.

Looks like your Backups.backupdb folder is owned by root, making it read-only for you. I'm not sure if those is the correct permissions (don't have my TM drive connected right now), but you can try changing it temporarily to see if it starts working.

You may also have to do a recursive change if all subfolders are also incorrect.

Ignore ownership would adversely affect recovery, as files being recovered would not have the proper uid/gid. Yes?

Repair permissions on the drive ran without anything being repaired. However, afterwards, the TM started up properly on that drive. As far as I can see, all perms are as they were before, including the root-owned dirs.

It's fixed, but I don't know or understand why! Also, apparently the root ownership is correct.

See,.........

this kind of situation is EXACTLY why I won't use Apples Icandy Time Machine for 'mission critical' backups!!

Actually, that setting is what is recommended by Apple. See this article: »support.apple.com/kb/HT5096

Read that again.. It says it should not be checked.

TamaraB is correct. You'll lose all of the file ownership in the backp if you enable that.
