Good morning gentlemen and Merry Christmas to you.
I would like your advise to the following matter that troubles me.
I am trying to find the optimum way to backup my OMV Server. My current data capacity is almost 11TB which are expected to grow even more the following months (current rate is approx. 1TB/18 months). Currently i have a backup of my files on a QNAP TS-421 and on two external HDD drives. The problem is that the QNAP is almost full and i don;t want to have my backup lying around in various places. I would like something "clean and tidy".
What i currently think are the following solutions:
1) Buy an external 12TB HDD drive which will be my main backup and format my QNAP to have is as an "expansion storage"
2) Buy an external case that will accommodate 3-4 HDDs. Buy one HDD of 12TB and as the size grows, adding more drives. This solutions also covers the "clean and tidy" part.
3) Build a new PC with the lowest CPU and RAM in a small case that will accommodate 3-4 HDDs, install OMV on it and have it as a backup server. This will also have the function of immediate use, if i have a hardware failure on my main server. I could use a raspberry pi and an external case for this solution as well
What is your opinion on the above?
My current server is an intel i5, 9th gen with 8GB of RAM running OMV, using four HDDs in snapraid+mergerFS
I would love to hear any other proposal as well.
