Backup and Restore
Full Backup / Restore
The best way to recover from data loss is to have a full backup of your machine. With this backup you can easily restore your machine to a working condition.
The procedure below explains how to selectively backup only the files essential to your MoinMoin installation. While there is no need to maintain both a full and a selective backup, having at least one of the two is strongly recommended.
If you want a backup of MoinMoin and your data, then backup the following:
moin configuration, e.g. wikiconfig.py
logging configuration, e.g. logging.conf
moin deployment script, e.g. moin.wsgi
web server configuration, e.g. apache virtualhost config
optional: moin code + dependencies; you should at least know which version you ran, so you can reinstall that version when you need to restore
To create a dump of all data stored in moinmoin (wiki items, user profiles), run the following command:
moin save --all-backends --file backup.moin
Please note that this file contains sensitive data like user profiles, wiki contents, so store your backups in a safe place that no unauthorized individual can access.
Backups require valid metadata to produce files which can be loaded
in particular, the size attribute must be correct for each revision.
if bad metadata is found during the backup,
there will be a warning logged and it is recommended
moin validate-metadata -a -f
see Validate and Optionally Fix Metadata
To restore all software and configuration files to their original place, create an empty wiki first:
To load the backup file into your empty wiki, run:
moin load --file backup.moin
Then build an index of the loaded data:
