The "Deleted data" filters can be used to completely remove parts of the backup - before comparison of the new backup to the currently stored backup, Unimus will REMOVE the matched data from the "new" backup. This means that this data will not be stored as a part of the backup at all - as if this data was not received from the device at all.

Filtering types

Line filters

For the line filters ("Line starts with" and "Line ends with"), if there is a match, the whole line is filtered / deleted.

These filters can be used for simple and easy matching rules if you know the exact beginning or ending of a line you want to filter / delete.

Regex filters

If there are no capture groups in the regex, the whole regex match is filtered / deleted. However if you use capture groups, only the content captured by the capture groups will be filtered / deleted.

This allows for very precise and flexible matching using regex and capture groups, so you can filter / delete only exactly what you need.

We have a blog article that offers additional details and a more in-depth description of how and when filters can be useful:
