baklabel 1.2.0

Baklabel delivers a daily label fragment for grandfathered backups

Baklabel is intended for use in automated scripts to deliver a sensible directory path fragment (or label) each day to construct a grandfathered local backup destination. It can also be run as a stand-alone utility to find the backup label produced for any given date and set of options.

Run baklabel.py -h to see command line usage options.

Call baklabel directly or import it and produce labels from your code.

Python 2.7 and 3.x

In the docs directory after installing, see release_note.txt for more detail on the package, instructions.txt for baklabel output examples and backup_howto.txt for a complete example backup script for Windows.

Properly grandfathered, there needs to be a daily backup to one of 23 separate tapes, sets of media or local directories on a storage device. This complement is made up of 6 weekday backups, 5 week backups and 12 month backups. 23 backups is quite economical for 12 months coverage.

This provides a stream of untouched backups for at least seven days plus the ability to go back four or five Fridays plus having monthly snapshots going back for twelve months. This represents real comfort when retrieving data which has been compromised at some unknown point in the past.
