Hi,
since some weeks I am setting up my OMV and I start to love it.
First I had it setup as Raid 1 - see here:
Changing Raid1 to 2 single disks
Now I have it with 2 single drives and I am thinking how to proceed.
a) Setup RSync or similar to protect my data
b) Setup a Snapraid to protect my data
I am planning to do a USB Backup on a large external USB drive from time to time as a backup. I know, RAID is not a backup
My use case:
I want to use it as a file server for my pictures (a little more than 1 TB) for my music (played via Volumio on a RasPi) and as a place to write backups from some Windows PCs.
What I like about Snapraid is the fact that I can just put in some more discs if space is getting tight and all shares are stay the same. This is not this simple in a single disc solution - I would reorganize all my shares and backup routines...right?
I am reading for some hours now and I learned that I have to have the largest disk as a parity disc. But what is the minimal HDD number I need for a setup with Snapraid to protect a single failure?
To make it short, here are my questions:
- for my use case, is it worth the effort?
- is it a good idea to use ext4 as filesystem?
- can I start with just 2 HDDs or do I need 3?
- What is the difference between data and content drives?
- Where do I find a list about usable space if I use 3 * 3TB discs for example?
Thanks for your advice/thoughts about it - or some links to get more information I am missing...and sorry for my English - not a native speaker...
Best.
Fabian
