We have a RHEL2 server that has had one of the drives in the raid array fail. I would like to do a full backup of the system before we replace the raided drive, in case the second drive decides to die during the procedure.
What is the recommended way to back up a linux system? I was thinking of doing a snapshot, but the system is ext3 with no LVM. It has been suggested to hook up a usb drive and do an rsync of /. Are there any better solutions?
The reason I wanted a snapshot is that I wanted to get an image of the disk, so that I wouldn't have to reinstall and reconfigure all the apps.
On an EL-2 system you do not have much in the way of 'snap-shot' technology and in the case of failed drives etc.. they wouldn't be much better than an rsync, dump, tar etc of the system.
rsync -avSHP --exclude proc / system2:/snapshots/system1/
