I've never actually wanted to restore my systems before. When something goes horribly wrong I try to do a vanilla install and then add old data afterwards.

At work I've had to do restores twice, on both times I was able to fiddle with disks and was able to transfer/restore the systems with dd/tar and some luck.

Two years ago I was involved in a "Disaster Recovery" exercise at work. The AIX box was up and running in under two hours, but because of a stupid Windows situation we were never able to get the Backup Solution up and running so we couldn't get the SAP data back on the system even after 48 hours. Not a great success...

Sometimes the simplest solution is the best. brbackup/brrestore is part of brtools that's part of the SAP executables under your exe directory. You can plug it into allot of different archive management solutions commercially available, or you can just use it stand alone. I/we currently use brbackup to clone and backup our entire SAP landscape from the smallest to the big honkin' 7 TB core FI/Logistics instance.

You only talk about system. Nothing about up-to-date system or personnal data. :)
Ok, minutes then.

I use udpcast .. That guy is a bull .. It can clone 192 PCs aprox., that is 16 PCs by each laboratory (12), in 50 minutes aprox. .. In theory, it can clone any number of pcs in the same time

I need to learn how to turn back the clock after I've screwed it up, rather than blowing it away completely and doing a clean install. I go repository happy and next thing you know I've gone from Lenny to Sid to who knows what and it's a total mess. LOL! Usually at this point the root password has miraculously changed,sudo is disabled and my account has no privileges. Obviously I'm still a newbie. LOLOLOL!

I was pretty smug with my collection of dd images and Bacula network backup setup. Alas, the "never tested" option ought to be there in bold, red letters.

About two weeks after a catastrophic disk failure on a W*****s machine, I finally had things restored. Bare-metal recovery takes a bit of planning and preparation, backup images don't always contain what you think they contain, and backup software configuration isn't always as straightforward as you thought it was (think catalog retention policy in this case).

I guess you can think about this either in the failure of a single machine or total catastrophic failure (fire, earthquake, etc.). I've had the former happen, but not the latter (*knock on earthquake retrofitted wood*), and the little bits of hand-built libraries holding things up definitely proved the slowest part and the biggest pain in the ass.

...1 minute / GB, approximately from a usb disk. Add the time it takes to reboot twice...

I utilize a quasi portable rsync script on all of my servers to perform a nightly seven day incremental backup. This script includes error checking so if anything is written to stderr, I get an email of its contents. This backup scheme works equally well via network as it does locally. This full system backup scheme has saved my a$$ more than once by allowing me to recover from a catastrophic failure in less than one hour.

P.S. Clonezilla is nothing more than a GUI front end for rsync.

I use "tar -xzvf" to backup my personal date :-)
I do not backup my system, all system crashes I use
as occasion to do some general changes in :-)

I use flexbackup to do the tar jobs then prepare them further for offline storage.

Not done an actual full restore for a while - last time of need was on a major upgrade - a partial restore was needed but lower level stuff had big changes.

Of course, RAID helps but is not foolproof - have to occasionally grab a file from a backup.

"Of course, RAID helps but is not foolproof"

Last time I had to do a full restore it was because I had two disks in my RAID array fail within a day of each other. Turns out, on investigation, that they were from a bad batch.

So, hint: don't rely on RAID, and source your drives from separate suppliers.

I use Fedora 9, and it rocks. I can recreate my production system from backups in an hour.

It actually depends on which TYPE of system. My development systems can be re-provisioned from a recent snapshot in under a minute since they're just VMs. My "real", stateful linux systems can be reconfigured in ~2-5 minutes from a recent tarball.

Everything else can be recovered from tape, external HDDs, but it'd take hours (especially for the windows systems -- *NOT* backup-and-restore friendly at all)
