I have just upgraded, to F23, a CentOS 6.7 system that has been
reliably running BackupPC (http://backuppc.sourceforge.net/) to back
up a Windows 7 system via SMB for several years.
After the F23 upgrade, which also included an upgrade of BackupPC to
version 3.3.1, backups are now always aborting at about the 8GB mark,
with this in the error log:
2016-02-28 14:00:02 Started incr backup on pelican (pid=325, share=C$)
2016-02-28 14:18:37 Backup failed on pelican (tar:712 Total bytes
received: 8287158228)
Actual byte count varies a bit from one failed backup to the next, but
stays at the 8GB mark.
Not sure this if this is a BackupPC issue, or something else. Maybe
filesystem-related?
More (possibly complicating) info; The destination for the backups is
NFS mounted on the F23 server from a ReadyNAS fileserver; local
filesystems on the ReadyNAS are btrfs format.
NFS mount shows:
raptor:/data/win on /win type nfs
(rw,relatime,vers=3,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.252.6,mountvers=3,mountport=60363,mountproto=udp,local_lock=none,addr=192.168.252.6)
Where to look? Thanks.
