Avamar: Best practices for backing up remote clients over a Wide Area Network (WAN)

A client backs up to an Avamar server using a low bandwidth or high latency WAN link. 

Since the client was activated, it has not been able to complete an initial backup.

The initial backup of an Avamar client is a full backup of the data. Any data which does not exist on the Avamar server is transferred during the initial backup. 

The larger the client and the narrower the 'pipe', the more likely the backup is unable to complete within the allotted backup window.

1. Copy the data to a portable storage device (such as a USB hard drive).
2. Install the Avamar software on a client local to the Avamar server.
3. Attach the portable storage device to the local client.
4. Perform a one-time backup of all the data from the portable storage device.
5. Start to back up the remote client.

When the client performs a backup, it only transmits new or modified data over the network. Since the bulk of data has already been backed up, the backup completes quickly.
