1) Windows FD has VSS support
That's interesting. It would be cool to have feature parity I suppose.
True, but there are many different filesystems on unices...
2) In case of ZFS/LVM you can run a pre/post scripts creating a snapshot
and mounting it for reading then unmounting and removing snapshot after
backup.
I suppose you can pack it into a python plugin but on first glance it
seems as a bit of an overkill.
I am trying to limit the amount of power the director has over my -fds
by allowing only backup and restores.
The "runscript" is a bit scary I think so I would prefer it if it can
be avoided by e.g. having a plugin.
But that's just my own threat model, it is OK if it is not shared by
other folks :-).
Perfectly understandable, but you still have to give the FD quite a lot
of privileges on the box for the backup job.
And - more importantly - even as a plugin you'd have to give the FD
enough powers to run the snapshot. So you might simply prepare the
script yourself.
I guess I could always have a /.snapshot/ directory in every supported
filesystem with a cron that refreshes it, and configure my FileSets to
only copy those files.
That would be an easy way to do it.
Was about to suggest similar thing :-)
Of course you have to remember of all the caveats that arise from the
asynchronicity between backup jobs and snapshot preparation.
