It's worth considering a filesystem that supports error 
detection/correction such as ZFS... Though to really make use of that 
you need to have a machine with ECC RAM. Not sure what all you have for 
a layout, but bitflips in backup data can make for a bad time.


Generally speaking I doubt you'll see a massive difference in 
performance from one FS to the other when dealing with Bacula. Where you 
really notice a difference is things like "deleting a directory with 
10,000 files in it" which is one area where EXT* performs very poorly.  
That however isn't a use case that you'd encounter with Bacula (or 
really any other backup system apart from maybe some sort of rsync-based 
setup).  Raw sequential read/write performance won't be massively 
different one FS to another; at most you're probably talking about a few 
percentage points unless you've got something like a badly aligned RAID 
array underneath it all.  Either way it's usually network bandwidth 
that's the bottleneck rather than disk, unless you're trying to do a lot 
of simultaneous I/O.

XFS was developed by SGI as a media system, and its design is optimized
for long streaming reads and writes.  Nevertheless, it performs enough
better than ext4 at short random I/O that both Oracle and PostgreSQL
recommend it over ext4 for database applications.

And that's for a usage type that it is NOT optimized for.  Bacula's OS
workload for storage is long, streaming reads and writes.  Exactly what
XFS *IS* optimized for.

You should be able to draw your own conclusions...

[Bacula-users] wiping test backups and starting again.

2015-11-01 Thread Thing 
Hi,

Reading the FAQ,

cd /src/cats
   ./drop_mysql_tables
   ./make_mysql_tables


Then just format the disk to wipe the volumes?

Anything else needed to do?

ps you could also remove what is it the working directory:

/var/bacula/working
or
/opt/bacula/working

though it is not critical

Yes, however, formatting the disk is a bit extreme, you can just go to
