Task #6711

Updated by bmbouter 8 months ago

Currently there are no docs about how to back up and restore a Pulp 3 installation.

* Create a page for backup and restore
* It should list all the components which needs to be backed up
* It should mention all the requirements and caveats (e.g. pulp version should be the same for backup+restore procedure, tasks in incomplete state needs to be cancelled, etc)

## Details

This should be a conceptual guide. We do not want to document how to backup postgresql in great detail for example. There are so many ways to backup postgresql. Similarly for

* Verify that
the filesystem, we can give a simple examples, but there are so many backup tools for files, e.g. `cp -a` `rsync`, or `rdiff-backup`, etc.

Overall the
written procedure is:

1. Stop all pulp services
2. Stop postgresql
3. Backup MEDIA_ROOT, e.g. `/var/lib/pulp`/
4. Backup Postgresql
5. If using S3 or Azure you'll need to archive that somehow.

To restore:
1. Stop all pulp services
2. Stop postgresql
Restore MEDIA_ROOT (with correct file permissions)
4. Restore postgresql
5. restore S3 or Azure
works
