Hi, We are starting up a backup consolidation project where we are going to implement TSM 6.3 clients in all our 100+ remote sites and having them back up over the WAN to a few well-placed TSM backup datacenters.
We have been through similar projects with selected sites a few times before, but this time the sites are larger and the bandwidth/latency worse, so there is little room for configuration mishaps ;-) One question always pops up early in the process: How are we going to do the first full TSM backup of the remote site nodes? So far we have tried: - copy data from the new node (include all attributes and permissions) to USB-disks, mount those on a TSM server (as drive X) and do a 'dsmc incr \\newnode\z$ -snapshotroot=X:\newnode_zdrive -asnodename=newnode'. This works OK and only requires a bunch of cheap high capacity USB disks, but our experience is that when we afterwards do the first incremental backup of the new node then 20-40 % of the files get backed up again - and we can't figure out why. - build a temp TSM laptop server, send it to the remote site, direct first full backup to this server, send it back to the backup datacenter and export the node(s). Nice and easy, but requires a lot of expensive laptops (and USB disks, the remote sites typically contain 2 to 10 TB of file data) to finish the project in a reasonable time frame. So how are you guys doing the first full backup of a remote node when using the WAN is not an option? - Bent
