[Bug 497732] Re: Tar exited with error 512 () status

[Neal McBurnett]

** Description changed:

+ A default install of backuppc produces fails on an hourly basis like
+ this:
+ 
+  Backup failed on localhost (Tar exited with error 512 () status)
+ 
+ because it is trying to back up /etc and several files there are not
+ readable by the user which is doing the backup (id backuppc).
+ 
+ Workaround: you can either ignore the failures via the --ignore-failed-
+ read option to tar, or grant superuser privileges to backuppc and do the
+ backup via sudo as described in comment #15.
