Here are a few things to check:
- can you manually create files and directories below /vol/bpc4/BackupPC
as the backuppc user (eg, "su backuppc; cd /vol/bpc4/BackupPC; mkdir foo;
rmdir foo; touch foobar; rm foobar")
- is the file system mounted readonly?
- has the backuppc user lost permissions?
It does look like the failure to update the filesystem exposes a bug which
I'll fix, but this is secondary to your main issue:
Can't use an undefined value as an ARRAY reference at
/vol/opt/BackupPC-4.1.3/bin/BackupPC_refCountUpdate line 380
