We currently use Ghost to take images of our Linux servers (a little out of date I know), and we are having a lot of issues with it.
Can any one suggests a good back up solution that will take complete system image like ghost from a running system. Is it possible to dump the entire file system to a tar file while the system is running? However I assume this is only a file level backup and does not contain the disk partitions and other system info.
this will not be a long term solution, we are looking at enterprise solutions, but that will be 6 months to a year before we can get them, so I just want a system that back up the server and easily restore to the same or different hardware.
Oh and if possible open source as I don't want to spend out lots of money now if we are getting a full solution in the not to distance future.
I looked at Baculas and Amanda, but was not sure what these could do and if there was a much simpler way?
