Hello,
In my opinion, using network mounted disks for backup is a risky
business. Bacula is designed to work with direct attached disks and
tapes, so when you connect them instead by a network, you introduce more
errors (networks have more faults than direct attached devices), delays
(latency), and buffering problems. Latency problems are particularly
bad for a SCSI device because it is a very chatty protocol.
Bottom line: a lot of people use NFS/CIFS or iSCSI, but I wouldn't bet
my data on them.
NFS tends to be very unfriendly with Bacula for two reasons:
1. If the NFS connection drops, Bacula can wait forever (something dumb
in the implementation) hanging on a system call.
2. If the NFS partition fills, you may not know about it until the
device is closed (end of Job) and then it is too late to do much of
anything.
Best regards,
Kern
Best regards,
Kern
