Backing up Linux Systems

Posted on 2012-09-10

We currently use Ghost to take images of our Linux servers (a little out of date I know), and we are having a lot of issues with it.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?

    Assisted Solution

    One good solution would be to use Clonezilla. I have not personally used it as I have not really had a need to backup a system outside of the enterprise, yet I hear Clonezilla is the best way to go; it is open-source as well.

    If you need a little assistance getting started with it, here is a great post:

    Can clone ziller back up a running system? don't you need to boot to a live disk so talking he service out of operation for the duration of the backup?

    Accepted Solution


    in my experience Bacula is one of the most reliable, and it offers enough options for every kind of backup. We used it for several years to backup linux and windows systems. The management is easy and the recovery of files is really a friendly procedure. Not too difficult to configure for Linux Sysadm.
    It can backup running system without any problem.
    The official website offers enough resources and the community is helpful.

    Hope it helps.

    I have looked at Bacula and while it is great it  is a bit OTT for what I was looking for.

    I found a lot of our system are running LVM to manage there storage and see you can script snapshots of this and then easy pull this of to disk.

    Makes backing up a few Linux server quite easy :)
