Restoring from backup #142

Closed westmorland1066 closed 5 months ago

westmorland1066 commented 5 months ago

I took backups of 2 instances through the octodeploy script (1.0.3) so I could do a fresh install of OctoPi 1.0. On my new Octopi/deploy server I create an instance with the same name as my old instance and then try to restore the backup and it fails with the error below. I get the same whether I try to restore from the command line or through the octoprint instance. Filename is Ender3v2-01_2024-01-11_backup.tar.gz

Uploading backup, this can take a while. Please wait...

Restoring from backup...

Restore failed! Check the above output and octoprint.log for reasons as to why.
Removing temporary zip

There are two separate backup systems: the native OctoPrint back, which creates a zip file, and the octoprint_deploy backup which creates a gzipped tar file. They are not compatible with one another.

Since you created your backup with octoprint_deploy, you can use octoprint_deploy to restore the backup. Place the tar.gz file in your /home/$USER directory, run octoprint_deploy and do a restore backup.

Ok, so that was dumb on my part.

So I went through octoprint_deploy restore backup. It unzips the files, though it complains about an unexpected End of File on one of them. I can see all the files in the directories, however, when I do a list instances under the Utilities menu it only shows the default octoprint instance. Neither of the restored instances are listed, and if I try to access them through the browser I get a 404 response. Rebooting the system didn't change that.

You need to recreate the instances (using the same instance names) with octoprint_deploy, then do the restore. This is described in the README file.

Thanks Paul. I don't know how I missed that. It's a great piece of software.
