Save Changes from read only Wiki

[AnthonyMuscio]

Folks,

I am researching turning the save mechaisium upside down. Basically from a read-only wiki storing changes in Local storage and backing them up. The idea is to facilitate a local backup of changes only, you can restore if it is lost in the browser. I am looking at a something like a bookmarklet that may store the location of the backups but It may be good enough to save in downloads like existing backups. I will provide a kind of logout button that commits the changes to local file, but otherwise not save to disk.

I am keen if anyone wants to help. I am thinking of those who already made a backup solution.

However my First Question

• I can make a bundle of changes that I save to file, however If I try and import it the safety mechaisium to "Blocked temporary state tiddler" and "Blocked system tiddler" force the user to select an override. I would like to have an import that does not do this, for this special case. any suggestions?
  Thanks

Since such a process will be unique to an address found in a browser, being able to generate a backup of changes using based on the url it was accessed by would be easy to reproduce eg from Tiddlywiki.com the file could be tiddlywiki.com.json

My current export filter is [haschanged[]] [enlist{$:/temp/BrowserStorage/Log}] !readme.txt
where !readme.txt can be reviewed before reimport import.
