I like rsnapshot, together with remote-shares it does what I want. So my questions are a summary of my experience the last eight weeks, because I like to understand how it is going and to avoide beginner faults.
remote-shares - Was a recommendation of subzero and you. I put in on samba, for some reason I doesn't understand, I was unable to switch on nfs on the same hardware setup. But as samba worked I did not further investigate in the nfs-issue .
Does it make sense to go for nfs instead of samba? What would be the benefits?
Sequence and manual starting the job is nice when initially filling. Its hard to figure out rsnapshot in the process list, as it starts rsync the same time.
"gui blocked" - When starting rsnapshop manually from the gui, a window pops up with two options "Start" and "Stop". After manual start the gui waits for finished or manual "Stop". Anything else of omv-gui is left behind unreachable.
Even with the wrong permissions of remote-shares, the copy is running with all files. Again, would nfs help to avoid these permission warnings?
Samba supports hardlinks, otherwise the utilization of the disk would blow up. Time-Backup was way faster, maybe they use some kind of database in the back what speeds up. But if there isn't a switch "slow-medium-fast", I did not find yet, I can live with that.
rsync after snapshot whould generate two copies of the original. rsnapshot on remote-share gives one incremental copy on a seperate server. That's better for me.
The problem with the process list, email notifications aso is not lack of information. It is too much information, where the important messages are difficult to find.
