I'm new to this forum and may be someone can help?
We use Retrospect 7.7.620 on Windows XP and a Dell LTO2 Autoloader as Backupserver. Local Network Clients use latest Retrospect Clients on Mac and Windows over ethernet or wifi. All of the local clients backup with more than 150MB/min.
Now we use Retrospect to backup our Windows 2008 webserver over internet (latest Retrospect Client). And this backup runs only with 10MB/min. All the time, this was ok, but now the size of the backup was bigger and the backup takes too much time. We dont use VPN, the connection is direct.
A year ago, we have a 16Mbit ADSL connection to the internet. (with ca. 12MBit down- and 4Mbit Upstream). Now we use a VDSL connection (28Mbit up, 7Mbit down). All the time, the backup speed was 10MB/min. We test another Windows Server (2003) by a different provider and again: 10MB/min. And that was only 1,7MBit/s. (the network display on both Retrospect server and client show the same: 0,15% network traffic on 1GB card). The download via http from the server is much faster (and reach the 28Mbit).
Network encryption in Retrospect on or off has now effect. And we have no network or backup errors, it is only very very slow.
Some more infos:
1. Backup to local file backup use the same speed. So LTO2 is not the problem.
2. We installed Retrospect 9 Demo on a local Mac and try to backup the Windows Server over VDSL to a file backup. And it runs with 80 or 90 MB/min. Great! Any chance to see a Retrospect Update for Windows in the near future??
