Hi all. I'm currently having a following problem: I have only ssh connection to a CentOS 5.2 system, there are two harddiscs on it. One stores the system (/ filesystem) and the other should be used to help restore the system in case of first disks' failure. I thought that maybe dump would be a good utility to make it. But in only works on read-only filesystems. In one article I've read that making a snapshot of the / filesystem (then it wouldbe read-only) and backing it could help. But aren't snapshots limited to logical volumes (LVM)? My friend told me to use rsync to back up the entire / filesystem to the second disk and then in case o failure the system from the copy should boot ok.
Could anyone provide any suggestions? I don't have physical contact with the machine so for example RAID 1 isn't a possible option/ Any help will be very kindly appreciated. With regards, R.
