Hi Forum,
Could you please advise if there is a way to create a backup of a system?
I added some packages to my router, and for example, if I want to bring through this config to another router, or have to recover from an issue, and I do a factory reset, how I can bring back the original configuration (with additional packages, config, credentials)?
I am not sure, whether the LuCi backup can restore all these ...
Thx in advance!
build your own image with imagebuilder including packages and config.
You can make system packages clone from the link provided by owut / auc.
Config backup is designed to cover all configs.
If you have extra data on USB, extra partition youll need to take care about it.
You mean, this one? https://openwrt.org/docs/guide-user/installation/sysupgrade.owut
Yes, I have an USB attached, I run a script which collects some hosts files, concat them, store the output on that USB, and symlink it to the router's hosts file.
So, if I am not mistaken, I can install owut on my router, and if I run: owut upgrade -a packageX packageY then will create a system snapshot?
is there a way to specify where to save it? LuCi can save to my Windows machine, can I do this via cli?
No, owut will create sysupgrade file with installed packages.
sysupgrade (also when ran by owut) creates tarball of config files listed via sysupgrade -l and stores it in overlay partition, then after reboot takes it to RAM, formats overlay and restores tarball.
You can add more file paths to /etc/sysupgrade.conf
But external storage will be mounted in same place untouched.
Hmm, ok. In that case could you pls help how?
Thx!
You want owut download to just create the image and plop it into /tmp/firmware.bin. That will contain target- and device-specific firmware with all of your installed packages. It does not contain the configuration backup, for that use sysupgrade --create-backup /tmp/backup.tgz.
I see ... so owut download creates a "snapshot" with all packages installed, and the sysupgrade backup (I think that's similar to the LuCi backup) saves the ''snapshot" config. Is this right?
If yes, if I want to restore, first I have to install the image created by owut download, then load back the config saved by LuCi or by sysupgrade.
Is there a way to specify the owut snapshot output? I think it won't be possible to upload to Windows, but for example to the mounted USB?
It is identical conf backups everywhere. sysyupgrade -l for the list.
Thx.
Is there a way to determine the owut downloadoutput? Like to a mouted USB?
You can redirect owut's image save file with the --image option:
$ owut -h
...
-i/--image IMAGE - Image name for download, verify, install and upgrade.
If you want to know the contents of the image, look in the manifest, which is normally beside the image /tmp/firmware.bin at /tmp/firmware-manifest.json.
Thanks for all the help, worked.
I created a backup to the mounted USB and copied it to Windows with WinSCP, did the same with the config backup.
Checked the .json, packages are there.
