#2141 Issue closed: Save the entire system to the single ISO image¶

Labels: support / question, fixed / solved / done

geksi opened issue at 2019-05-09 13:58:¶

For small systems, is it possible to save the whole system to one single ISO image? Business case - restricted DMZ with no backup, nfs, etc.
Thank you!

Yes,
because it is possible to have the backup inside the ISO image
(usually the ISO contains only the ReaR recovery system).

See what "man rear" tells about BACKUP_URL=iso://
e.g. online at
https://github.com/rear/rear/blob/master/doc/rear.8.adoc

It is even possible to spilt it onto more than one ISO image,
see what usr/share/rear/conf/default.conf reads about
ISO_MAX_SIZE

But I have no personal experience with using BACKUP_URL=iso://
so that I don't know about the details here - I had tested it once, cf.
https://github.com/rear/rear/issues/1545
but I do not use it regularly in practice.

In https://github.com/rear/rear/issues/1545
I had used this /etc/rear/local.conf

OUTPUT=ISO
OUTPUT_URL=nfs://10.160.4.244/nfs
BACKUP=NETFS
BACKUP_OPTIONS="nfsvers=3,nolock"
BACKUP_URL="iso:///mybackup"

but in a 'restricted DMZ with no backup, nfs, etc'
OUTPUT_URL=nfs://10.160.4.244/nfs cannot work.

I think OUTPUT_URL=file:// or OUTPUT_URL=null
(see "man rear") could help in this case.

Alternatively you may think about using
OUTPUT=USB and BACKUP_URL=usb://
see "man rear" and have a look at
http://relax-and-recover.org/documentation/getting-started
and see the OUTPUT=USB stuff section in
usr/share/rear/conf/default.conf

Because "no news is good news" I assume it is sufficiently answered.
