This weekend I had a major problem... I managed to delete my backup of my documents.
Usually no trouble but I'd just formatted the PC. Thus I lost everything. Long story short, I cant get the docs back (so this years uni work gone and all 20Gb of my music) as it was an Ext3 formatted disk and I made a boo boo about backing up to DVD (last time was about month and half before this accident)
Anyhow, my webserver does have some room for expansion. Basically I was thinking of backing up my docs to it (benefit I can also access it from uni via my FTP server)
BUT
to keep it low power, I was gonna add either Compact flash (via IDE/CF adapters) or USB keys (both in around 4Gb flavours as it's only docs not music I'll backup)
Now I know flash memory is prone to being restricted in the number of writes so I was looking at possibly backing up to a RAID array.
Now is RAID a good option? From looks, I'd be after RAID 1. And with RAID can I only select 2 drives to be a copy of each other? I don't want the main CF card (and the current hda) to be part of the RAID array.
Basically I need to sit down and completely rethink my backup strategy. It was to backup to my portable HD anything that is in my docs and delete from the backup anything that wasn't (hence how I deleted it all...I ran the wrong script) and once a week backup to DVD.
Unfortunatly, the DVD thing feel behind so I need to get back in the habit of doing that but can anyone suggest something?
I was thinking of daily backups to the webserver where it's RAID'd and nothing is deleted at all. Then backup what ever's on my Docs to my portable HD (so they're syncd) and then a DVD to top it off each week. Is that good enough?
