I am trying to do LVM snapshot backups.
Whatever option I use, thus far, Tar will "complain" that all
directories have changed from one backup to the next.
Two identical commands except for the output file:
tar -cvvf /backup/local-first.tar -g /backup/local-first.lst
--atime-preserve=system -C /snap . &> /backup/local-1.log
tar -cvvf /backup/local-second.tar -g /backup/local-first.lst
--atime-preserve=system -C /snap2 . &> /backup/local-2.log
Done off of two different snaphots.
Output of the second log file:
tar: .: Directory has been renamed
tar: ./bin: Directory has been renamed
tar: ./games: Directory has been renamed
tar: ./include: Directory has been renamed
tar: ./lib: Directory has been renamed
tar: ./lib64: Directory has been renamed
tar: ./lost+found: Directory has been renamed
tar: ./man: Directory has been renamed
tar: ./sbin: Directory has been renamed
tar: ./share: Directory has been renamed
tar: ./src: Directory has been renamed
And so on.
It will simply recreate all those "changed" directories in the new
archive, effectively storing all the same files.
Is there a solution to this?
tar (GNU tar) 1.28
Oh, never mind. I think I found the --no-check-device option. I had
remembered reading about it but I forgot.
Damn this has been hard again....
Regards.
