We have three dpm servers in our organization that we've set up for Windows XP client backups for now. The system appears to work fairly well, capturing most backups per the policy window. I've been observing the behavior of the backup for our travelling
workforce and have found that some backups do occur over their vpn connection, but others do not. What is the behavior of the travelling computer exactly? We had thought that it would cache snapshots at the policy specified time and then update the server
with a big synchronization that would populate the days that they missed. However, this doesn't seem to be the case. What happens when my laptop is on, but it's not connected to the network (for days or weeks)?
With Vista and Windows 7 clients, if the client is disconnected from the network when a sync is scheduled, a local shadow copy will be created on the client and the user can still access these to do EUR. When the client connects to the network again it will
sync with DPM. However, XP does not support the kind of VSS snapshots that allow for local end user recovery so when performing client protection for Windows XP local snapshots are not able to be created and cached.
