My back up: i have two asian guys who write down all my data on paper.
I have a 80GB external that I backup most personal critical stuff on. Otherwise I burn onto DVD's about every other month all else. My home computer doesn't have much on it other than games so other than my game saves I'm not that worried about it. It's my work PC that carries the bulk of important stuff and it's automatically backed up each night.
My backup strategy involves waiting until I lose my data and then sulking.
RAID 1 here!
Not picking on you but you do realise that raid 1 on its own isnt a backup strategy? If data becomes corrupt then its mirrored on both hard disks. There was a large blogging site that went down this year because they only had the information raided and they lost the lot.
I have raid 0 in my computer and backup to a sata usb caddy which lets me stick any size sata drive into its housing then copy all my important files off. The drive then goes safely on a bookshelf. The caddy is like a big plastic box with a letterbox style flap - the drives just slide in. Its alot cheaper than buying a portably hard drive.
To protect from hardware failure, I make sure all my data exists on more than one spindle. My day-to-day files get backed up daily from my desktop/laptops to my file server. Big things like media files or installers are stored on the file server. Everything on the file server is mirrored weekly to a second server. To protect from stupidity, I use stuff like shadow copies, incremental daily backups going back a month, and periodic snapshots to dvd for important files. Still need to look into using something like LiveMesh or DropBox to get some offsite backups too.
On my Mac laptop I have an external drive just for Time Machine backups.
For all my important documents I have a dropbox account, linked to 2 machines. So I have the important documents on 2 machines and online.
For everything else I have a very ugly and inefficient way of keeping things on multiple hard drives and in multiple machines.
All important apps I use in servicing other PC's are in my USB drives. Others I burn to DVD.
I got three machines at home. My main backup is Buffalo 500GB with LAN interface. Each machine is also subscribed to online backup service (2 with Mozy for free 2GB account and 1 with Carbonite for paid unlimited account).
I use a Home server that weekly backup my 6 computers in around the house. I also use my ftp server to back up homework i do at school (cant trust people on the public bus when im carrying around a laptop).
I used to have 5 HDD's that had 5 copies of everything for years. At one point i delete everything and sold the drives.
At this time, i only have pictures on 2 dvd-rw's that i update when ever i have more pictures, and my job resume that i keep up today when ever needed.
Other then that, i dont have anything to back up or worry about losing. I can always download everything else if needed.
Photos are stored on two different machines, each machine then has a backup drive for those pictures. Everything is backed up monthly on an external drive and stored in a fireproof safe.
There are 2 ways that I backup my main computer. I have a second spacious drive. That makes it easy to do a perfect backup in one of 2 ways:
1. I have an old emergency Ghost 2003 bootable emergency CD/diskette. When it is time for the weekly backup (to back up the entire disk that includes the operating system and files), I simply restart the computer with either the diskette or CD and have it backup the C drive to a specific folder as image files on the D drive.
2. If you have either at least one Seagate or Maxtor drive, then you can download free of charge software from Seagate's site(they own Maxtor now). Using that software you can burn an emergency bootable CD. Like in step one, you can boot off of it and save the entire C drive into the D drive as one image file. You can also a sector by sector backup, but this is not necessary.
In both steps, if the main hard disk fails, you easily reboot with any of the emergency CDs after replacing the C drive hardware with a new drive. Within one hour, the main drive is completely restored and you do not have to configure anything. I have had this happen last year and step 1 CD made the restore simple.
I use Allway Sync 'n' Go. It does a pretty good job at comparing filesystems. Of course this is for using where edits can be found in multiple places (portable HDD, thumb drive, etc).
I've just ordered another 1TB drive to continue backing up stuff. Unfortunately it's become a bit of a habit, although I'd rather be over zealous, than lose everything.
As far as music & photos go. I have those in 3 or 4 locations. Ya never know, and it would SUCK big time to lose all that.
I dont have one ;p
I run Cywin with SSH & rsync and backup to a friends computer. I have a backup of his data and he has a backup of my data. If my house burns down I still have my data over at his house. We both had available storage so the cost was $0. I'm running Windows 7 and he's running Linux.
I have a RAID1 configuration in my desktop computer and an external eSATA HD using Windows 7 built-in backup utility. Additionaly some data is also on CD/DVD/USB.
I have two external 1TB drives I use to backup my photographs..
After 10 years of shooting digital photos and have over 50,000 - 60,000 photos. As of now this is the only way that works for me, each drive contains a copy of my photographs. My biggest concern is if something happens in my home I could lose these backup drives and then lose my photos.
I wish I could use a online backup, but could never deal with the cost of 750 MB of require storage space for my photographs. Each month my requirements of backup space increase because I shoot some more photographs.
I have a 300 gig external hdd that I backup my my documents onto periodically. Also have some cd/dvd backups of some files/programs I really want to keep, and are had to find. I don't really backup my games and anime I have on my computer. I know its not the best backup setup, but it works for me.
For work we have a server setup as raid 1 where all out files our kept, then also have it copy to a 300 gig hdd in another computer, that then backups via Carbonite. We would have it backup straight from the sever to Carbonite, but it wont let you backup from a newtwork drive, and they don't have a copy of their backup client that will run on Linux >_< . Only Windows......
I agree. Using services like drop box and skydrive are an awesome backup tool for the really important stuff.
I wrote about it here : http://www.evilmunky.com/?p=1277
Hard drives are cheap these days!
I added a second internal HD and I use the Magic Backup online service to automatically backup any changes to my entire Documents and Settings folder daily.
The first back-up take some time but the daily, (changes only) backup takes just a couple minutes and is done in the background so you don't even notice it.
Online backup is the only way to go in my opinion. Hard drives are nice, but to vulnerable to real life threats. I like a true backup software like backazon.com Be careful for just "sync" sites that are passing themselves off as "backup". You need versioning to be a good backup.
