I would like to know whether rsync can be relied upon as a full system backup.
For example could I backup the entire root partition, and restore it to a freshly formatted new disk and that would work?
This hinges on being able to backup or copy files that are in use or 'open' files.
My searching on google for this seems to come up with the answer of 'sometimes' and 'it depends on the operating system' and such.
Anybody found the answer and are using rsync for system backup? or just data backup?
