Dear All,

I’m having issues to run image backup for Linux Server. Below is some details of my configuration.

OS: Rocky Linux release 9.6 (Blue Onyx)

This may be an odd question, but why the odd text in the backup? Why not just /dev/sda ?

I know nothing of Image backups on Linux as I stick to file backups. But in my case I just type the path normally.

Dear BatterPudding,

Thanks for pointing this out. I was entering /dev/sda as the volume to backup. After save it and go back and check, it auto become that odd text.
