About a month ago I upgraded my BackupPC server from a older Linux
release to a new one. The BackupPC package is BackupPC-3.2.1 from
EPEL.
Unfortunately, the backuppc UID changed, and the permissions in the
cpool were not correct. So I got a lot of these kind of errors:
BackupPC_link got error -4 when calling MakeFileLink(/coraid/BackupPC/pc/gto/260/f%2f/fhome/fasist/f.gconfd/fsaved_state, 9c3096761bd4daff1d2321fadbef16b5, 1)
The backups looked like they were working, so I didn't fix it right
away. I just now finally got around to fixing the errors by fixing
the permissions on the cpool directory.
However, I imagine I now have a lot of wasted space due to all the
linking that did not occur while the permissions were wrong. And I
think that BackupPC_link removed all the "NewFileList" files,
despite that the linking failed.
So, is it at all possible to force the linking to run again? I
tried just doing
${BACKUPPC_PATH}/BackupPC_link hostname
But it just looks like it exited right away -- as I said, I think
because the NewFileList files are gone.
If it's not possible (or practical) to rerun the link process --
will the wasted space basically gradually go down when future
backups occur (assuming future linking works)?
