  1. :: Purpose:       Rotating differential backup using 7-Zip for compression.
  2. :: Requirements:  - forfiles.exe from Microsoft
  3. ::                - 7-Zip
  4. :: Author:        vocatus on reddit.com/r/usefulscripts
  5. :: Version:       1.4.7 - Removed some redundant %TIME% stamps in the logs, under the Cleanup section
  6. ::                1.4.6 + Added two additional "help" flags: "-h" and "--help"
  7. ::                1.4.5 + Added better instructions for what variables can be set to
  8. ::                1.4.4 + Added quotes around variables that could contain spaces in a few places
  9. ::                    * Some comment cleanup, and some logging formatting cleanup.
  10. ::                1.4.3 / Tweaked logging to only display exclamation point if there was an error
  11. ::                    / Tweaked logging to display time correctly (no extra spaces)
  12. ::                1.4.2 / Some logging tweaks
  13. ::                1.4.1 / Some logging tweaks
  14. ::                1.4   + Added quotes around SOURCE variable that were missing in a couple places
  15. ::                1.3   * Fixed backup archiving - wasn't rotating properly on network paths. We use pushd to get around this
  16. ::                      - Added "-s" option to show job options that the script WOULD execute with
  17. ::                      - Major overhaul of code order and logic. Stuff should break less now.
  18. ::                      - Many fixes to exclusions file checking
  19. ::                1.2   - Fixed problem with cleaning backups. Now cleans staging area and long-term destination area.
  20. ::                        Normally an archive (-a) switch cleans the staging area, but now the -c switch does as well, just in case.
  21. ::                      - Also fixed issue with forfiles.exe not being able to read UNC paths. We use pushd to get around this.
  22. ::                        Pushd auto-assigns the next available drive letter to a UNC path, then discards it when we use popd.
  23. ::                1.1   - Added option to use an exclude file to specify files/folders to exclude from the backup
  24. ::                1.0b    Some tweaks to logging
  25. ::                1.0     Initial write
  26.  
  27. :: Notes:         My intention for this script was to keep the logic controlling schedules, backup type, etc out of the script and
  28. ::                let an invoking program handle it (e.g. Task Scheduler). You simply run this script with a flag to perform an action.
  29. ::                If you want to schedule monthly backups, purge old files, etc, just set up task scheduler jobs for those tasks,
  30. ::                where each job calls the script with a different flag.
  31.  
  32. :: Usage:         Run this script without any flags for a list of possible actions. Run it with a flag to perform that action.
  33. ::                Flags:
  34. ::                 -f   create full backup
  35. ::                 -d   create differential backup (full backup must already exist)
  36. ::                 -r   restore from a backup (extracts to your staging area)
  37. ::                 -a   archive (close out/rotate) the current backup set. This:
  38. ::                      1. moves all .7z files in the %DESTINATION% into a folder named with the current date
  39. ::                      2. deletes all .7z files from the staging area
  40. ::                 -c   clean up (delete) old backup sets from staging and destination. If you specify a number
  41. ::                      of days after the command it will run automatically without any confirmation. Be careful with this!
  42. ::                 -s   show job options (show what the variables are set to)
  43.  
  44. :: Important:     If you want to set this script up in Windows Task Scheduler, be aware that Task Scheduler
  45. ::                can't use mapped network drives (X:\, Z:\, etc) when it is set to "Run even if user isn't logged on."
  46. ::                The task will simply fail to do anything (because Scheduler can't see the drives). To work around this use
  47. ::                UNC paths instead (\\server\backup_folder etc) for your source, destination, and staging areas.
  48.  
  49. :: TODO:           
  50. ::                1. Add md5sum checksum file in the backup directory (md5sum each full and diff and store in a file)
