[Feature request] Backup limits

[vatterspun]

Current behavior:

The program will backup versions of files until it starts going above a certain level, after which you can throw it into a zip or 7zip file. Since the media you may back up to may be limited, it becomes necessary to manually go into the folder or archive and delete old versions.

Requested behavior

Any one of the following could help mitigate the issue:

• File iteration limits (e.g. only backup X versions of a given file, discarding the oldest when it reaches the limit)
• Individual file limits (e.g. only backup any individual file in a set until it reaches X megabytes, discarding the oldest when it reaches the limit)
• Total backup size limits. When the limit is reached, the oldest file, regardless of which one, is deleted.
