Creating a backup of your Wiki pages

All your Wiki pages reside in the directory /wiki/data. Every Wiki page is in it's own file. The file name matches the Wiki page name. The uploaded files are stored in the directory /wiki/upload. It would be sufficient to backup these two directories.

The older revisions of your pages are in the directory /wiki/history. Every file name corresponds to the name of a Wiki page or an uploaded file. All files in this directory have an unique numeric file name extension. Decide for yourself if it is worth keeping older revisions in your backup. It is advisable on an open Wiki, otherwise you might realise too late that someone edited an important page and saved it empty.

In the directory /wiki/trash are the deleted files; both Wiki pages and uploaded files. Make a backup if you are running an open Wiki.

In any case: ignore the cache in /wiki/cache.

Storing static pages

Simply generate static web pages using the menu item 'Extra'. You will need to copy these directories for a backup:-

• /img - which contains the images (logo) used by PWP
• /css - conatining the style sheet (a lost style sheet is unimportant)
• /static - where all static HTML files are
• /static/upload - which contains a snap shot of all uploaded files

Static pages do not contain Wiki mark-up. They constist of 100% static HTML. If you backup only static pages, you might loose your Wiki mark-up!

The static pages can be copied on CD-ROM or every other medium. All path entries inside the static pages are relative (Unless YOU did link images using an absolute path, see FAQ).

File time and FTP backup

PWP features like RecentChanges, etc. are based on the file attributes created and last modified. An FTP based file transfer exchanges only the file contents itself - not the file attributes. If you backup your Wiki data using FTP, all time based file attributes will we set to the current time, i.e. all files have been created and modified recently.

A workaround might be to store your data files in a zip archive and transport the zip file via FTP.
