Slow Back Up Speed - Linux Server
Hello,
I'm having a speed (lack-of) backup issue on a server with BEWS 10d rev 5629. The backup server (media server) backups about 12 servers. All of these backups run at a normal, acceptable speed, except for one. The problematic one is a Linux server, and it runs at about 3 MB/min (compared to >400 MB/min on the other ones). The media server does not backup any other Linux servers, but in other subnets I do have other media servers that backup several Linux boxes at regular speeds. Note that we are using the Legacy UNIX/LINUX Agent on all these Linux hosts.
The configuration of the backup job is the following.
Here is the troubleshooting steps we've taken. We tried backing up to both disk and tape. The speed is the same. We've run the job at different times of day and night. We've restarted the remote agent. We've rebooted both the backup and linux servers. We've checked the physical connections, replaced the ethenet cables. The most revealing test is when we ran a file copy using WinSCP between the servers, and that ran at a normal speed, above 1 GB/min. So it all seems to point to the backup application.
Here are the servers' specs.

The configuration of the backup job is the following.
- backup account has root access on the linux server
- back up to disk
- backup method: Full - using modified time
- no verification
- Hardware compression
- No Advanced Open File
- Open file backup when AOFO is not used: Never
- Network and Firewall: Use any available network interface
