If you are comfortable using SSH and running basic unix commands, (cd, vi, cat, tail, grep, etc.), then my recent experience may help you out. Naturally, if anything goes wrong, I am not responsible. Back up anything before changing and seriously, if you have never used Unix on the command line, just ignore this post.
/etc/cron.d/WDSAFE is the crontab for the safepoint job. This is the scheduled job (or jobs) that kick off your backups.
/usr/local/NSPT/WDSafe contains the executable script (safeptExec.pl) and libraries (in lib) that run the job. The script has a debug option, which you could add to your cron entry, but it doesn’t look like it logs a lot.
If you check out the key library CopyHandler.pm, you’ll notice that the core of the operation is based on rsync:
rsync -rtDviH --delete --progress from to etc…
/etc/mtab is your mount table - this has a list of drives to mount at startup. In it you may see an entry like this for a drive you are using to backup to:
//IP_ADDRESS/SHARE_NAME /media/WDSAFE/MOUNT_TARGET cifs rw 0 0
The second path is where you can physically access the remotely mounted drive. If you head over there, you can list the contents of the SHARE_NAME. You should see everything that has been safepointed before.
Finally, your safepoint config files are held in /DataVolume/cache/WDPROT/WDSAFE. Under safepts, you will find a file with MOUNT_TARGET as the name and you can check the config here (IP_ADDRESS, SHARE_NAME, etc.)
Anyway, if you are struggling with failed safepoint backups, you can just try running an rsynch in verbose mode to see where it trips up. Unbelievably, I had a number of music files with bad names. They had an apostrophe in them, which was not windows compliant. How I ever got them on my PC, I will never know, because if I tried to change the name and cancelled, Windows woudn’t allow it. Weird. Anyway, after going through this process a number of times, I got all the names fixed and it works fine. The bad charcter I found was ’, wheras windows only allows ’ and `.
rsync -rtDviH --progress “/DataVolume/shares/Public/Shared Music” “/media/WDSAFE/SHARE_NAME/”
Note the trailing slash.
Some other useful files:
/etc/nas/NSPT has the exclude file and other config files
/etc/nas has some other files you may want to check out
/var/log has a couple of safepoint and other log files that are vaguely useful
/etc/trustees.conf I made a note of this, but can’t remember why
