    [SOLVED] Manual incremental backup

    Hi all,

    I've had a look at some backup systems, including Amanda and Bacula, but what frustrates me to no end is the (apparent) inability to initialise a manual backup with any of these systems. Having to backup to virtual tapes is also very frustrating to say the least as I'm running a RAID array with no need for tape backups.

    My scenario is as follows; I have a Windows laptop which connects to the network at completely random times, and as such it is futile setting up a cronjob on the backup server, since there is no way of telling when the laptop will connect to the network again, nor the duration of it's connection.

    I need some method whereby I can implement an incremental backup on this laptop, but the user must be able to manually initialise these backups.

    A gentle nudge in the right direction would be much appreciated.


    [edit] I guess the only reason I stuck this under the Ubuntu Server section is because the backup server is running this distro.

    Re: Manual incremental backup

    Well, without actually having done it ...... I see at least 2 options.

    1. Assign your laptop a static IP on the network. Write a small script that peridically looks to see if that IP is pingable, then initiate the backup when it sees that IP avaialble.

    2. Install Cygwin on the laptop, and write a small shell script that initiates the backup. You could just use rsync, or rdiff-backup (for actual incremental backups). Put a desktop link to start the script.

    Probably several other ways to skin that cat!

    Good luck!

    I would do:

    (1) install cygwin with ssh and rsync

    (2) write a small script that will backup your notebook to the server using rsync and then "duplicate" with hardlinks to create an incremental snapshot-style backup

    Thanks guys I didn't know about cygwin. I've just checked it out, and this will make life a lot easier. Thanks!

    if you want to use rsync, ssh and hardlinks, have a look here:
