Performance extremely bad, help me find the problem
Hello everyone!
Backups are taking too much time so I think there must be some kind of problem with our configuration.
The backup server, also where the Acronis management console is installed, is fast: 6 core Xeon, 8GB ram ecc, RAID 6 with LSI card, etc.
Before going productive, we're backing up an infrastructure server (monitoring snmp, flows, etc) that doesn't compromise business. We could say this is a "test server" although is a real server.
The "test server" is an HP Proliant 180G6, same as most of our productive servers. Quad core xeon, 32GB ram, RAID 1 and single disks. Total occupied space: 400GB.
We ran this backup twice already, the first time was cancelled at 38% after 12 hours or so. Current backup is taking 21 hours 38 minutes and is arround 46%.
- All servers run windows server 2008r2 or 2012r2 Operative Systems.
- Our backup policies requires "full backups", once a day everyday.
- Backup is being made to a network share. Two switches appart from each server. Gigabit speeds. IN and OUT of business hours. Almost no load on those switches.
- If you copy a bunch of data from the "test server" to the backup server vía shared folder, you get a 110MB/s sustained speeds.
- CPU & mem usage remain low in both servers.
- Network usage in both servers is incredibly low, averaging 10 - 20 mbps speeds.
- Network usage between switches is very low, almost exclusive to the backup operation.
I don't know where to look. I don't seem to find any indicator of a problem.
Any input that could shred some light is welcome!
Regards,
Agustin.
