manciaux Posted July 30, 2003 Report Share Posted July 30, 2003 My windows server 2003 performance drops precipitously when I run a Retrospect backup. If I do a backup during the day, the Exchange Server and SQL Server performance seen by clients is horrible. Is there a way to force Retrospect to run at a lower priority. Is the performance expected to degrade this badly? Link to comment Share on other sites More sharing options...
natew Posted July 31, 2003 Report Share Posted July 31, 2003 Hi, How many execution units are you running at once? What happens to RAM usage when retrospect is running? Thanks Nate Link to comment Share on other sites More sharing options...
manciaux Posted July 31, 2003 Author Report Share Posted July 31, 2003 1 execution unit, RAM goes to 40MB or so (machine has 384) Link to comment Share on other sites More sharing options...
natew Posted August 1, 2003 Report Share Posted August 1, 2003 Hmmmm What are your disks doing during the backup? Pretty busy or not? How about backing up a client machine rather than the server- is the server still slow? BTW- What is your backup device? Thanks Nate Link to comment Share on other sites More sharing options...
Mikee Posted August 1, 2003 Report Share Posted August 1, 2003 HI. Performance can be affected by three things: Hard Drive - read and write contention RAM - disk swaping CPU - programs do not get enough of CPU time In your case I bet it's Hard Drive contention. It's a given if you are running SQL DB, Exchange and Retrospect on one PC. Plus the amount of RAM is too little as well. What kind (SCSI/IDE?) and how many drives do you have? Under Task Manager, what does the memory usage show (Physical available, Commit charge total...)? Mikee Link to comment Share on other sites More sharing options...
