Hi Wee
I run a setup of SAM-FS for our main file server and we loved the
backup/restore parts that you described.
That is great to hear.
The main concerns I have with SAM fronting the entire conversation is
data integrity. Unlike ZFS, SAMFS does not do end to end
checksumming.
My initial reaction is that the world has got by without file
systems that can do this for a long time.
Indeed. Progress is one-way like that...
..so I don't see the absence of this as a big deal.
Except that it dilutes the ZFS promise to, "we can keep your data
safe... unless we have to restore any of it from a backup." It's a
big deal if you want the integrity promise to extend beyond the pool
itself! Or so it seems to me.
