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.
Can I simply add a new disk of the same size and restore with a button click?
Can I use multiple smaller disks and restore to those rather than one larger disk?
If you really like SnapRaid, go and ask Andrea at his (SnapRaid) forum.
I've heard FlexRaid also supports Linux (including Ubuntu, Redhat, SUSE, Zentyal, OpenMediaVault, and many others).
How are you liking it on windows? What are the sync times like?
I also use Snapraid on my windows media server and use Junction folders for pooling. A "poor mans" storage and pooling solution
Sync times are based on your read/writes speeds of your hard drives so it varies. If the hard drive can read at 100MBps and the parity can write at 100MBps then you should get 100MB a second for a sync. I've never seen a sync that was unusually slow except for my hard drives that are 99% full. A snapraid check will take around 5hrs to complete if I remember correctly. I have three 2TB HDD with 2 full and 1 half full. Doesn't hurt to try out, if you don't like it then you can just delete the parity and go with something else.
You don't install Snapraid, its run like a portable program. Its literally just deleting your parity (right click, delete) and deleting the Snapraid folder. Snapraid also creates a content file that you specify where its placed but its a single file, right click and delete.
