When I do a backup of a system, after the backup has finished I get
Error -4. Line states time BackupPC_link got error -$ when calling
MakeFileLink(/backuppc/pc/computername/0/directory/filename. What could
be causing this error. Everythign seems to be functioning correctly
just see the eror when i view the log. I get this on backuppc beta and =
release version. I thought I did somethign wrong so I completely
reinstalled it just to test it out.
Currently just running it on a few computers to test out to see if it
will fit our needs.
This means BackupPC couldn't create a hardlink from one of the new
files to the pool. The three most likely reasons are:
- /backuppc/pc/computername is on a different filesystem to
/backuppc/pool or /backuppc/cpool. Use "df /backuppc/pc/computername",
"df /backuppc/pool" and "df /backuppc/cpool" to be 100% sure they
are one the same file system.
- the /backuppc file system is either full or out of inodes.
Use "df -i /backuppc" to see your inode usage.
- some permissions problem: perhaps /backuppc/pool or /backuppc/cpool
(or the directories below /backuppc/cpool) are not writable
by the BackupPC user. This could happen (although unlikely
because of all the error checking) if BackupPC was run as, say,
root, and then later run as the usual BackupPC user. The
directories created by root will not be writable by BackupPC.
The backups are still ok, but these errors mean that BackupPC is unable
to save storage by linking to files in the pool. So you should fix it
before doing a lot more backups. Also, once you complete your testing
you should start over will a clean pool etc.
