And I disagree with you, because if you do not have RAID, you loose the data
instantly and in best case your backup is a few hours old. Plus you have
the effort to restore probably the last monthly, then the last weekly and
then few incrementals - compared to replacing just one disk and letting it
resync.
In general I agree with you that both are essential, but if someone asks me
I definitely recommend RAID and in addition the backup.
This means if you want to be able to restore let's say yesterdays version of
a file.
True backup is very costly if you want to do it the proper way. For example
you shouldn't have the backup in the same room - cause in case of fire ...
you know what I mean. I wouldn't spend that much money on it.
As the question was about NAS ... it looks like you need two - one for the
data and one for the backup
So I appreciate and share your opinion, but here it is not an enterprise
consulting company I guess ... although with 40+TB ... :D 22 of them in
use ... I doubt that avg. user has high demand on backup such large
volumes. AS shown in the example with deduplication you can use even an
external disk as backup device to keep large amount of backups.
All I want to say is setting priorities and calculating the risk makes more
sense to me.
