bak Folder
The bak folder contains all backups of the site in compressed zip files. The backups are created with the Special:Snapshot and the pages. They contain
- the code in the site folder as site.zip and siteYYYYMMDD.zip
- the revisions by thousands as revisions-N000.zip (using parameter revisions)
- the files ordered by revision by hundreds as files-n00.zip (using parameter files)
- the log files by month as logs-YYYY-MM.zip (using parameter logs)
The following folders are not backed up as they can be recreated: cache, current, indexes queries.
The aim is to make ftp download easier when there are many files or many revisions. At this time there is no restore function implemented yet.
