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.

Well, I see, but it's odd this would occur just when the F23 upgrade was done. The last prior backup to the upgrade was a full backup; what's failing now is an incremental. Would've thought a filesize limit would've been hit before. Thanks.
