Maverick_94 Posted March 11, 2008 Report Share Posted March 11, 2008 Hi, When the server backup a computer, the speed is very slow, about 10mb/mn. I checked with a simple file transfert and the transfert speed was 3.5-4Mb/s. Is there a solution to increase speed ? Thanks Link to comment Share on other sites More sharing options...
Mayoff Posted March 11, 2008 Report Share Posted March 11, 2008 You need to give more details. What version of Retrospect? Is this a local backup or a network backup? What type of network? Wireless/Wired/Over the internet What is your backup device type? How is the backup device connected to the computer? How fast is your computer? How much RAM do you have? Details please.

Maverick_94 Posted March 11, 2008 Author Report Share Posted March 11, 2008 Sorry, I am going to give you more details. You need to give more details. What version of Retrospect? 7.5 Is this a local backup or a network backup? This is a network backup What type of network? Wireless/Wired/Over the internet Wired. What is your backup device type? A network hard drive in the same rack than the server in a gigabyte network. How is the backup device connected to the computer? Through the network How fast is your computer? Between the server and the computer, the speed is good, about 3.5mb/s. How much RAM do you have? 2Go. Details please. Done :tongue2: Link to comment Share on other sites More sharing options...
Mayoff Posted March 11, 2008 Report Share Posted March 11, 2008 These details do help, but I am still unclear what you are doing. Are you trying to backup the same computer running Retrospect or are you backing up a network of computers to this network device? How much data is being copied? How many total files? What happens when you back to a local disk instead of to the NAS device? If you want the best speed, write to a locally attached disk and not a network disk. All Retrospect logs report performance in MB/Minute. What exactly does the operations log say for the copy performance, compare performance, total duration, Idle/loading/preparing time. The operations log has all of this info. Link to comment Share on other sites More sharing options...

The operations log has all of this info. There are about 50 computers in my network. There are the server and the network hard drive on which I store the RDB files in a rack. I save 5GB of datas on each computers, it's a lot of files. When I backup a local hard drive or another server in the rack, the speed is very good.

Maverick_94 Posted March 26, 2008 Author Report Share Posted March 26, 2008 I also saw that backup on LTO3 is limited to 500mb/mn in a gigabyt network, it's pretty slow right ? Link to comment Share on other sites More sharing options...
Mayoff Posted March 26, 2008 Report Share Posted March 26, 2008 The use of an LTO3 is going to be limited by the speed of the source itself. Doing local backup, you should get between 1000 and 2000 MB/Minute. Pulling data from the network will impact the speed. The total number and size of files will also impact speed.

mauricev Posted April 18, 2008 Report Share Posted April 18, 2008 Between the server and the computer, the speed is good, about 3.5mb/s. I'm not sure what you are trying to say here, 3.5 megabytes per second or megabits per second. But even if it were megabytes that is abysmally slow for a gigabit network. So it sounds like you have a problem with your network. I would first verify that you are indeed running gigabit and then ensure that the duplex settings are matched on all the computers.
