I think that this quick test is a much better than, say, pinging
the source in a pre-exec script: this tests not only that the
source is up and connected to the net, it also verifies (1) that
ssh is up and accepting our key (if we are using ssh), and (2) that
the source directory is mounted (if it needs to be mounted) and
readable.

Subject: Notiz: Probleme mit Ampersand in source
Date: Tue, 07 Oct 2008 16:11:10 +0000
Hoi Nico
Kleine Notiz wie im IRC besprochen:
- Hat es in /etc/ccollect/sources/$BACKUPNAME/source ein Ampersand muss
dieses Escaped werden, da sonst folgender Fehler auftritt:
*snip*
[volumes_ForschungEntwicklung] 2008-10-05-03:10:03: Beginning to backup,
this may take some time...

[volumes_ForschungEntwicklung] 2008-10-05-03:10:03: Finished backup

[volumes_ForschungEntwicklung] 2008-10-05-03:10:03: Warning: rsync
exited non-zero, the backup may be broken (see rsync errors).
*snip*
- ein "&" im Namen fürs Backup,
also: /etc/ccollect/sources/volumes_Forschung&Entwicklung/ wird beim
Anzeigen (wie oben zu sehen) verschluckt.
Cheers,
Tiziano

1. I got a syntax error in ccollect.sh once in a while, i think at
rollover. I changed the line
j=$((j+1))
to
j=$(($j+1))
(twice) and the error went away.
