    From ReaR log:

I'd like to know how to specify the parameter -allow-limited-size in ReaR configuration.

Sorry, I would like to backup all files into 1 single ISO. So if that possible to make that iso file large than 4GB?

@crazy90cc Please start using rear-2.0 on RHEL 6 as 1.17.2 is too old. Version 2.0 is also supported by RH. And, yes it should be possible to make a single ISO image bigger than 4GB.

Hi dgha,

Finnally i have make the 1 single iso. But i realized that rear will make the iso into directory /var/lib/rear/output, and after that will copy to the OUTPUT_URL location. How to make that clean the directory /var/lib/rear/output itselt? Or just directly copy the iso file to OUTPUT_URL?

@crazy90cc See also issue #734 and try to make OUTPUT_URL=null and I never defined the BACKUP_URL=iso://cifs/path -> did it work? I always used a path on a local path on the system with enough disk space.
