Hi Liste, 

I am using Bacula for years now and had no trouble so far. 
But now it really hits me.
Well it worked smoothly .. until restore. (on ubuntu 12LTS and ubuntu
14, bacula version 5.2.6)
The files were on USB disk. To be on the safe side I recreated
everything on local sata again. Same result.
I do tons of rsync on that disc with no problem, checked with smart,
upgraded the system and no change. If I run bacula-sd with -p the
restore is pulled through but the files are really corrupted.

Luckily I have another backup. But this is really a bad move.
How can I rely on the backup of bacula now? (i.e. Rsync tells me at
once if the file is corrupt) Do I really have to do a checking restore
on every job now?

Could you give me a hint what might be the problem?
Thanks
G.
