[Bacula-users] Volumes marked with Error

[Bob C. <bob...@pu...>]

Hi,
       I am running the following

Director, Storage deamon 2.2.6. The library is an Overland Arcvault 24 
(LTO3)
Most clients (about 30 ~ 8TB in total)  are 2.2.4

Backup are running through fine, but occasionally a volume is marked 
with status Error when it is nowhere near full. The backups using the 
volume at the time give no errors. Restores from the backups using the 
volume are also OK.

I am losing a lot of tape capacity from this however sometime the tape 
is marked as Error  when only  a  few Gig has been used.

There is one thing that I thought may have a bearing. I am using a 
mixture of spooled and non spooled backups. Some of the backups are on 
old hardware, consist of lots of very small files (several million  ~1Kb 
html files ) and the resulting very poor throughput can result in a big 
shoeshining problem - I generally spool these. Other ones are large 
database files with good throughput so I run these direct to tape. The 
spool files can be as big as 80Gb.

The director allows four concurrent jobs, I have two tape drives one of 
which is generally Incrementals only the other Full backups only.

Can there be a problem if a spool file is despooling and a "direct to 
tape" job also need to write to the tape? Should I spool all my jobs?

Any advice would be very welcome.

Thanks

Bob
