I do have a question regarding Webmins Filesystem Backup feature. I configured it using dump to weekly doing a full backup and daily an incremental backup. Once it is running on a 2 CPU XEN guest the load is jumping up to 3. That's on a machine used for web and email hosting.
Although it probably is no big problem having a load of 3 I rather would avoid it. My idea is to let a second XEN guest doing the backup by creating a LVM snapshot volume of the hosting volume and backing up data from the snapshot volume. This also has the advantage of non changing data during the backup process. The second XEN guest is configured to use fewer CPU resources so it hopefully may not affect the first XEN guest much. So far so good.
Question is: Can I copy the backup configuration created on the first XEN guest to the second one?
The second XEN guest is not running Virtualmin because I don't want all the features like Apache, database etc. on that machine. May be I'm trying to be too puristic in that point? Shall I just install Virtualmin or Webmin only there and being happy to use the Webmin GUI? What do you think?
