Hi all

I'm planning a Bacula setup with ZFS on the SDs (media being disk, not tape), 
and I just wonder - should I use a smaller recordsize (aka largest block size) 
than the default setting of 128kB?

Also, last I tried, with ZFS on a test box, I enabled compression, the lzjb 
algorithm (very lightwegith and quite decent compression). For 'normal' data, I 
usually get 30%+ compression with this, but for the data backed up with bacula, 
it didn't look that good, compression being down to 3-5%. Any idea what might 
cause this?

Vennlige hilsener / Best regards

roy
