I am trying to migrate from one server (Webmin 1.585, Virtualmin 3.92.gpl GPL) to another (Webmin 1.590, Virtualmin 3.92.gpl GPL). I created backups on the first server from within Virtualmin and had it FTP them to the second server. I got the message “13 servers backed up successfully, 0 had errors. 7 Virtualmin configuration settings backed up successfully.”
On the new server, when I try to restore them, I select the directory that all the backup files are in and click on “Show what will be restored”. Step two shows all of the domains and a list of things that will be restored, however when I click on the “restore now” button at the bottom of that page, I get the following error from every domain I try to restore:
"Starting restore of 13 domains from local file /virtualmin_backups/12-07-09 ..Extracting backup archive files …
… extraction of /virtualmin_backups/12-07-09/domain.com.tar.bz2 failed :
sh: -c: not found
/bin/tar: This does not look like a tar archive
/bin/tar: Exiting with failure status due to previous errors
… failed! See the progress output above for the reason why."
I can see that this is, indeed, an existing file, and I can open it and view all of the contents using my file manager connecting over FTP. All of the files have the following permissions:
-rw-r–r-- 1 root root
How can I debug this error message?
