  1. How fast are your network backups?

    Hello David, sorry for the late reply. We use the Retrospect Client on the backup client machine. The smb speed is only for a comparison. We have similar speeds with 1GBit ethernet like you. We need to get more speed and upgrade to 10GBit ethernet, not only for the backup of course. But it seems, that Retrospect can't benefit from the faster network as we like. Our latest test comes near to 6GB per Minute which are 100MB per second. And I think it should be more possible with all this hardware. Maybe there is a software limit in Retrospect. Kai
  2. Hello, we are testing the new Retrospect 14.5 on mac as new server backup solution. Our plan is to use Retrospect Multiserver on MacPro with 10.12.6 and 10GBit network connection to backup data from Hyper-V Windows 2012r2 virtual machines which are also connected via 10GBit ethernet. Data and backup sets are on FC Raids (8GBit). If we connect to vm from MacPro via Windows smb share, we get a speed up to 700MByte per second read and write. Our first tests with Retrospect results in network speeds of max 4GB/min (backup and copy) which seems to be much slower than 700MB/s. Do you reach faster network speeds? Did we something wrong? Have a nice day Kai
  3. Very slow backup over internet

    No idea? Nobody?
  4. Very slow backup over internet

    Hello, 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. Any ideas? Thanks Kai Dittberner Update: 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??
