Time Machine restore problems (permissions)

[jukkaforss]

Hi,

I am making Time Machine backups to my Ultra 4 (RAIDiator 4.2.19).
Backups are working fine, but I can't access my backups to restore data.

When I press Enter Time Machine, OS X mount Time Machine backup correctly.
I can go Backups.backupdb directory, but not able to go Server_Name directory (No permissions)

Server-Name:Backups.backupdb root# ls -al
total 16
drwxr-xr-x+ 5 root _unknown 204 Dec 17 14:25 .
drwxr-xr-x 6 _unknown _unknown 374 Dec 16 23:28 ..
-rw-r--r--@ 1 root _unknown 6148 Dec 17 14:25 .DS_Store
drwx------ 2 root _unknown 68 Dec 17 01:38 .spotlight_repair
drwx------ 2 root _unknown 68 Dec 17 14:21 .spotlight_temp
drwx--x--x@ 34 root _unknown 1190 Dec 17 14:21 Server Name

If I try to add read permissions to Server Name directory, I get Operation not permitted

Server-Name:Backups.backupdb root# chmod og+r Server\ Name/
chmod: Unable to change file mode on Server Name/: Operation not permitted

If I use sudo in terminal to be root and go inside of Server Name directory, I see my backups correctly.

Inside of ReadyNAS same looks like this:

readynas:/c/.timemachine# ls -al "Server Name.sparsebundle"
drwx--S--- 4 ReadyNAS nogroup 4096 2011-12-17 15:18 Server Name.sparsebundle

-rwx------ 1 ReadyNAS nogroup 0 2011-11-22 00:06 token
readynas:/c/.timemachine/Server Name.sparsebundle#

Does anyone know how to fix this?

From looking at my NAS, I think the permissions on the following four files are wrong:

Code: Select all

-rwx------ 1 ReadyNAS nogroup 445 2011-12-17 14:06 com.apple.TimeMachine.MachineID.bckup
-rwx------ 1 ReadyNAS nogroup 445 2011-12-17 14:06 com.apple.TimeMachine.MachineID.plist
-rw------- 1 ReadyNAS nogroup 499 2011-11-22 00:06 Info.bckup
-rw------- 1 ReadyNAS nogroup 499 2011-11-22 00:06 Info.plist


There should be rw (not executable for the owner), read privileges for the group and read privileges for everyone on those files.

I would suggest disabling Time Machine on your Mac, correct these permissions and then try accessing your backup again.

Hi,

I changed that.


-rw-r--r-- 1 ReadyNAS nogroup 445 2011-12-18 16:05 com.apple.TimeMachine.MachineID.bckup
-rw-r--r-- 1 ReadyNAS nogroup 445 2011-12-18 16:05 com.apple.TimeMachine.MachineID.plist

But no change of this inside spersebundle directory, and not even root permissions to change it.

Were you able to resolve it? I am facing the same issue.
