Curious to see what people are doing for the data that resides on their UnRaid servers. With the increased incidents of ransomeware infections, its important people backup their data and have offline copies of their data. The 3-2-1 rule for backups states you should have three copies of your data backed up to two different kinds of media (so external hard drive and cloud, or some combination of the two) and one copy should be offsite. So if you don't currently backup the important data on your UnRaid server, seriously consider do so, sooner than later.

I only do the "3-2-1" with about 15% of my data - mostly for the practically priceless (e.g. absolutely no way to get it back if lost).

 

80% is on "P-Ro" arrangement (nice name?  ). Parity + Read-only. Write access is strictly on mc / Krusader basis.

I don't feel there's a need to have more than 1 copy of The Sopranos on separate devices, for example. If lost, it would be a pain to get it all back but any permanent data loss is ok.

It is possible to extend this to a "P-R-O" arrangement: Parity + Read-only + Offsite (see what I'm doing there?  ) but in my case it will take more than 3 months to get there so I'm sort of "nah". 

 

The remaining 5%, I do restrict access based on users but access is rw. 

See a single vote so far for the "wrong" first answer. Whoever it is should definitely reconsider.

I only backup a small portion of my files.  Most (by size) are recorded TV shows most of which I can record again if I loose them so I don't back them up.  I have about 250-500GB of data I have on multiple unRAID servers and offline drives for the important stuff that I can't get back.
