monacotek Posted September 3, 2008 Report Share Posted September 3, 2008 Hello, I just deployed a new backup server and have found that with compression enabled, a backup runs at 1/3 the speed as with it disabled. I would expect it to take longer, but is this typical? I also notice only one cpu core being used, but only about 60% usage. The files it is backing up are mostly large (up to 1.5GB or so) photoshop and tiff files. With compression off, performance is 1,800MB/min, with it on it is around 400-500MB/min. 300mbps and 90mbps lan usage respectively. The backup server is win 2003 with 2 quad core 2ghz xeon cpus, 4gb ram, and is storing the backups on a 10TB 3ware based array, and is connected to the network via 2 gigabit connections ("teamed" via LACP). It's running 7.6 multiserver. The server it is backing up is win 2k a single dual core 2.8ghz server connected with 2 gigabit connections (LACP as the other). It is a file server only.

Richy_Boy Posted September 10, 2008 Report Share Posted September 10, 2008 I would have thought with all the CPU power and RAM to hand it may be quicker to compress the data (in memory) then write the uncompressed data to disk across the network. I'd certainly recover the data to another location and check it's all present though for a bit of peace of mind. Rich Quote Link to comment Share on other sites More sharing options...
