I've removed my custom Rsync argument modifications, restarted backuppc daemon and rerun the backup.

Bingo. I have the same error in "dmesg -T" output: [Mon Nov 2 18:53:41 2015] rsync_bpc[910]: segfault at b49fabec ip 080918ca sp bfdc4a60 error 4 in rsync_bpc[8048000+75000] But I get this error even if i use default backup options with no previous V3 or V4 backups. :-(
If i do an fresh backup (default options, deleted the old backup folder) using the tar method (so the rsync_bps is NOT used), I'm unable to finish the backup too: backuppc@backup:~$ /usr/share/backuppc/bin/BackupPC_zcat /var/lib/backuppc/pc/mail/XferLOG.0.z |tail Got fatal error during xfer (BackupPC_tarExtract exited with fail status 11) Backup aborted (BackupPC_tarExtract exited with fail status 11) BackupFailCleanup: nFilesTotal = 0, type = full, BackupCase = 6, inPlace = 1, lastBkupNum = BackupFailCleanup: inPlace with no new files... no cleanup Running BackupPC_refCountUpdate -h mail -f on mail xferPids 3270 BackupPC_refCountUpdate: host mail got 0 errors BackupPC_refCountPrint: total errors: 0 xferPids Finished BackupPC_refCountUpdate (running time: 24 sec) Any ideas? I'm considering rollback to V3 backuppc :-(.
