Hi,

 

I would like to suggest a new feature(s):

 

Data Mirroring

I would like the option to replicate a folder to multiple disks. I am thinking of moving my family pictures over to my unRAID server, and while there is protection in the parity disk, these are important enough to me that I would like to keep at least 2 copies on my unRAID server (or have the option of replicating them to multiple disks). I would only serve up one copy via a share, but this would give extra redundancy for really important data.

 

Disk Mirroring

Given the cheap nature of disks it would be great to able to pair up disks in unRAID to mirror the data of an entire disk. Given that I can have 12 disks in a server, I would be willing to sacrifice 1/2 of them to provide a mirror of my primary disks as this still gives me 10TB of usable space (plus replicas, parity & cache drive). I could probably do this in the MB BIOS for the on-board SATA, but would prefer unRAID to manage it.

 

The ultimate idea for Disk Mirroring would be if unRAID could monitor both disk copies so that when I access a movie unRAID could determine which disk is less utilized and present that to the client. I have no idea if this is possible, but it would be great. Theoretically I could have the same movie running on 2 seperate TVs at different points. 

 

I am sure this sucks for timing as you are closing in on a RC for version 5, but this would be an awesome addition for down the road.

 

Thanks

Bill

You can create a set-and-forget automated script to do this if you wanted.

 

you could set up a chron job to rsync driveX to driveZ. you could then have it run whenever you want (once a day, twice a day, every hour.. etc.)

 

perhaps someone could create a plug-in for this as you are not the first person to ask this.

Thanks for the suggestion.

 

Do you have any recommendations on how or where I would go to figure out the syntax for the script? I am a Windows guy and this is my first Linux based computer, and it's been more than a decade since I used UNIX for anything.

 

A plug-in would be ideal. I figured others must want this same functionality as well.

 

 

Hmm.. if someone does write this plugin it should probably have some cool default options such as:

 

[ ] Sync /flash to [spare drive] [# of copies to keep]

[ ] Sync /mnt/disk1/mysql to [spare drive] [# of copies to keep]

[ ] Sync /mnt/disk1/thumbnails to [spare drive]

[ ] Sync [custom folder 1] to [spare drive]

[ ] Sync [custom folder 2] to [spare drive]

[ ] Sync [custom folder 3] to [spare drive]

[ ] Sync [custom folder 4] to [spare drive]

 

[ ] Execute daily [time]

[ ] Execute weekly [day-of-week]

[ ] Execute monthly [day-of-month]

 

[ ] Notify if backup fails [e-mail address]
