Hey guys, I’m setting up my NAS (openmediavault) and very much enjoying it! It now runs my Nextcloud and a couple of services. I got a mirror ZFS setup of two 8TB drives.
I got another two 8TB drives and am doubting whether I should add them as an extra mirror vdev, or create a new pool for extra backup. I’m not sure if that extra backup is necessary though, since I got a cloud backup already every day. My drives are only used 14% so I’m not even sure if I should already put them in the pool. What do you guys think?
A mirror array is not a backup. So therefor I would use at least one of those extra drives for a weekly backup of your data. You want some sort of not real-time backup in case you get cryptoed for example
That is true, but I was indeed not counting it as such, I currently just have the cloud as a backup.
WTF is an extra HDD?
Primary rule of thumb is 2 physical backups and one offsite backup(cloud). Remember physical medium can fail or degrade
I understand, but I was thinking, since I have a cloud backup, if my drive(s) fail I cam still always recover, correct?
What if the cloud server corrupts your data in transfer or worse shuts down its server without notification. It can and has happened.
For example, I had a cloud backup went to get it and the server could no longer be found. That was with Dropbox mind you. I lost 10gb of important files because of it. Never trust just one source of backup. Always have a secondary just in case.
Is it ok to ask what sort of data you have?
