[flexbackup-help] Error while unavailable samba mounted directory

[<twi...@ti...>]

Hello.

I have a trouble with backing up samba shared directory.
I wrote my own script. First, it will mount shared direcotry and than it 
runs flexbackup.

And the problem... While flexbackup is working and user reboots the PC,
flexbackup crashes with samba error, but it creates an archive and $? in 
Bash is equal to zero.
So everything looks fine, but next day, when I will run flexbackup with 
-level incremental,
it will work normally even the full backup isn't complete...

Can anybody know how to solve this?

Thanks.
