Good solution for offsite backups using TSM on a slow link.
Posted on 2008-10-28
We are currently looking into removing tapes in our offsite offices and use WAN backups instead. These backups will be done using TSM to a central office. Problem is, the initial backup is way too big for our current WAN links. Here is the solution we came up with:
1- Go physically onsite and copy over the data to a laptop (ROBOCOPY) and keep the same folder structure
2- Go back to the central office and install the TSM client on the laptop using the offsite server nodename
3- Backup the data on the laptop to the TSM server on LAN
4- Install the client on the offsite server
5- Configure the TSM client to use the same nodename as we did on the laptop in dsm.opt.
6- Configure the scheduler so it would only take incremental backups.
But that didn't work. We ended up with a full backup been taken on the first scheduled backup (first site had a good link so that's ok). So my question is how do i make this procedure work???
