I used to use a raid5 setup but was burned twice during recovery by URE's so thats been abandoned.
I'm running ubuntu.
My current disk setup is as follows:
- one 3tb storage drive for movies.
- one 1tb storage drive for music/temporary storage
- one 1tb storage drive for personal assets like family photos/videos, documents, etc..
- one 3tb external drive to backup the movies drive
- one 2tb external dive to backup the two 1tb drives
Now I have at least one more 1tb drive laying around maybe two. My movie drive is almost 100% full. So its time to either buy a couple more 3tb drives (expensive) or re-setup my storage solution to better make use of the space.
Let me tell you what I like about my current setup:
- I know which files are on which drive.
- If one drive dies it dosn't take my other media offline with it.
- Easy to tell which drive needs replaced and where to find its backed up date for restore.
- I know for sure my backup drives are powered off and not wasting their life span just sitting doing nothing.
I have been considering flexraid as it offers both protection and pooling but I dont absolutely need to have pooling.
The main goal is better use of the drive I have + simpler managment. Right now I power up the external drives and run my backup software about once a month because I'm lazy.
I'm fine with a snapshot type solution which is basically what I'm doing now.
So it seems really simple to me to see if there is a way to use my one 2tb backup drive as a storage drive as well as my other 1tb unused drive? The 3tb backup drive could be used as a parity drive. Keep in mind though I want to make sure that if for some reason say my parity drive + another storage drive fails that all my other data will remain safe and accessible. Also keep in mind i need to be able to set this up without losing any existing data in the process.
