Rename backup filename

Hi,

we get name this “vitalpbx-1678762769.tar” after backup by GUI.

there is no any word or name about server.
so we always very confuse what name for any servers.

it is littlebit danguerus when we working restore by GUI.

please add some name or rename backup file name.

such as

vitalpbx-1678762769-{{hostname}}.tar

vitalpbx-1678762769-{{tenent}}.tar

thanks
