Create/restore backup archive from CLI

[lleachii]

What is the CLI syntax to generate the same tar.gz config archive made in LuCI (e.g. to use the file list, etc. that LuCI does)?

Also, if it's possible, can the command the archive to /tmp

(I've search and looked for this specific answer for years; and just never asked - feel free to post a link to a relevant thread if one exists. )

Also, what's the command to restore the archive from the CLI?

sysupgrade -b /tmp/backup-${HOSTNAME}-$(date +%F).tar.gz

        -r | --restore-backup <file>
                     restore a .tar.gz created with sysupgrade -b
                     then exit. Does not flash an image. If file is '-',
                     the archive is read from stdin.

Just to add onto this, sysupgrade -h is the magic bullet:

# sysupgrade -h
[…]
        -b | --create-backup <file>
                     create .tar.gz of files specified in sysupgrade.conf
                     then exit. Does not flash an image. If file is '-',
                     i.e. stdout, verbosity is set to 0 (i.e. quiet).

Cool!

Thanks!

I never knew (vaguely recalled) that was a part of the sysupgrade program (woulda never thought to do -h on that program)!

I was trying to search anything that had tar.gz - and was getting a lot of results.
