Good point. You aren't going to do any major restores over that WAN. Plan on keeping a spare SERVER box at your TSM site. If the remote site crashes, recover it to the spare locally, and then overnite the box!

Are your recovery requirements full system (in which case it might take you hours or days to recover...), or only specific data directories? What would your customers *need* in order to get their systems back up and running? It's a battle I constantly have - getting our users to give us their *recovery* requirements, as opposed to what they believe their *backup* should be...

One option might be to look at centralised servers, but if this is not possible, then you need to work out the best speed your network link will provide say 100 mb. an hour for 256k and base your plans on what is possible. Oh and of course get management and the users signed up to whatever service level you can provide. Maybe one backup a week might concentrate a few minds. good luck John Neil Sharp <[EMAIL PROTECTED]> Sent by: "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> 26/10/2004 16:04 Please respond to "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> To [EMAIL PROTECTED] cc Subject Tips on backing up over slow networks please Has anybody has experience with backing up over slow N/W's (min. 256k)? Unfortunately the clients are NOT Windows boxes so I can not use adaptive backup or journaling features. Currently I am not aware of the daily change rate of data on each system. My initial thoughts are to perform a staggered initial backup and then once complete implement a daily incremental backup. Things that I am looking for would be advice on the best performance tuning parameters to use.
