Question

Recently presented the idea of using TWiki at my company which was received v. well (big surprise for my archaic company).

One of the concerns was how the data is stored in revision control and was sort of space this takes up.

Are there any special measures designed to ensure disk space is saved.

Is anything special performed when saving attachments in revision control.

Any info to alleviate any concerns would be gratefully received.

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

TWiki topic data is just text, very little space is used even if you count in all versions of all topics. For example, the Codev web with 4800 topics consumes only 88.8 MB space, or 18.5KB in average per topic.

The main factor are the number of file attachments and their size. If you plan to use TWiki to store CD images you will consume lots of space. For average collaboration such as the Codev web you might consume between 2 to 10 times the space of topic data. The pub dir of the Codev web uses currently 780 MB, or 160 KB per topic in average.

There is currently no way to turn off revision control on attachments. I would not advise to do that anyway; complete audit trail and history is needed in a corporate setting, and disk space is cheap.
