What are you using for your backup system?
I don't follow the 3-2-1 rule all the time. 3 copies of data, 2 different devices and 1 outside the house.
My Big Boob stuff goes to a Synology NAS DS 415play with 4x 8 TB WD Red without further backup ...
For my private data I use a Synology NAS DS916+ with 4x 10 TB Ironwolf Disks.
Videos and photos go there directly ... also without backup yet.
For important data I store them locally on the PC and the data are replicated with Synology Drive into my private cloud on the DS916+. It is similar like OneDrive for Business.
This means I have 2 copies this way. I also have setup Active Backup for Business todo daily incremental backup of the OS and Data drives, also going to the DS916+. Then from time to time I backup this important data to a drive connected via USB 3.0. My gap so far. I don't store it outside the house.
The other gab is that the Video and Picture data don't have a backup yet. This burns on my nails, most right now. But with this new WS I will include internal disks and copy all the videos, there and then setup the Synology drive again. That moment I have 2 copies. But still I wouldn't have a copy outside, because I don't have the free disks anymore .. ;-)
I consider a 3rd Synology NAS, sooon. A DS1019+ which should come out soon. Then I will migrate the DS918+ to the DS1019+, the 415play to the DS918+ and the DS415 play will be used as backup device for the data to be brought outside.
