Hi, now that my OMV NAS and the backup computer are more or less stabilised (i.e. at least I can access them at much better speeds, the HDDs are pooled meaning that I won't accidentally miss out folders during backup and that the backup computer contains a second copy of the files in NAS. Yes, I know, this is not exactly a backup by sysadmin standards...), I now need a bit help planning my next moves.
You see, I will like do the following with their respective reasons:
1. SnapRAID: It seems to me that most people using pooled HDDs pair their systems with this. Also, the idea of having some form of redundancy by just adding a new HDD for every 4 HDD and not needing to rebuild the array is quite appealing
2. rsync: I understand this is a better way to copy files from one computer to another since this is an incremental sync rather than full sync (e.g. FreeFileSync). I do still want to see the files being changed before initiating rsync.
3. rsnapshot: I understand that this is what most people use as part of their backup strategy and is also a more true backup solution (e.g. allowing going back to a week's ago data). I am still quite unsure of how to implement it properly.
4. More space: I can also forsee myself needing more space, will have to consider this too. Each computer has 5TB, I hope to have at least 6TB.
So, I will need some opinions on the following:
1. In which order should I proceed?
2. What hardware changes I will need to get? (e.g. How big should the new HDDs be? Need to consider getting better machines in long run?)
Thanks!
