I am planning on setting up a FreeNAS-based storage solution. It'll be mainly for storage of large data files in a lab/research environment. No databases, just plain files. Most of the data is added, only a part of it is edited/changed over time. Network connection is Gigabit ethernet. I need about 10 TB of usable storage.
One of the requirements is that data is saved twice. So I am considering setting up two similar systems with 5 3 TB disks in RAIDZ1 . System 1 is then the system that users connect to, and makes regular snapshots. System 2 would be the backup system. System 1 sends its latest snapshot to System 2 after office hours. In the end, this should give me regular snapshots on System 1, and daily snapshots on System 2.
Being totally new to this, I was wondering if this makes sense, and if this fits within the standard FreeNAS capabilities. Suggestions for improvements are of course welcome as well.
An alternative would be to only store the most recent nightly snapshot of System 1 on System 2, but I'm not sure if it really has a large advantage in terms of required disk space.
Also, does FreeNAS automatically removes old snapshots when the disk fills up?
Thanks for any insights!
Best,
Koen
