A question on compression

[Matt Emmott]

Hi,   I’m running Amanda 2.4.2 p2 on a Red Hat 8 server. The backups were set up before my time, and I’m trying to wrap my head around how the compression is set up & why it isn’t working for some backups. We’re backing up 2 clients – One is a Red Hat server running Amanda, and the other is a Windows server that I connect to over a Samba mount at /home/windows_server_name. It’s the Samba mount that isn’t compressing.   My disklist file is set up as follows – the backup server name is “backup”, and the Linux server that I’m backing up is called “falcon”   backup /home/windows_server_name/folder1 user-tar backup /home/windows_server_name/folder2 user-tar backup /home/windows_server_name/folder3 user-tar falcon /var/folder1 comp-user-tar falcon /var/folder2 comp-user-tar falcon /var/folder3 comp-user-tar   And here’s the part of my Amanda.conf that specifies the type of backup:   }   define dumptype comp-user-tar {     user-tar     compress client fast     index yes }     However, in the backup emails, where it shows the compression percentage, the Windows server shows no compression (shows up as --), and the Linux client shows up in the 15-22% range. So, what is the best way to rectify this?   Thanks! Matt
