Simple Timemachine

Motivation

• When playing Neofly in Microsoft Flight Simulator, the Neofly app saves the progress to one file only and replace the old one. I want to have a history of saved files, in case I need to restart the progress after crashing the plane.
• I was able to do it manually (by renaming the file), but why not to have an automated agent that can copy the file to a backup location and rename it, according to timestamp

Technical Proposal - MVP

1. Agent will be able to monitor a folder for a specific file pattern. When there is a new file (eg file that was not backuped yet), it creates a copy of that file in a backup folder with a new name, created as orig_file_name_without_ext_YYYYMMDD_HHMMSS.orig_extension
2. In order to keep the load on the system low, it should check new files only every sleep_time seconds
3. Configurable items
   • monitored_folder
   • monitored_pattern
   • backup_folder
   • sleep_time

Nice to have

1. Logging to the log file (no more debug prints)
2. The configuration will be done through json file
3. The name of config file or the section in the file can be parametrized through cmdline
4. All configuration parameters through cmdline
5. Agent will monitor several folders

Installation

pip install appconfig-json
### Alternatively, use test channel
### pip install -i https://test.pypi.org/simple appconfig-json -U --no-cache-dir

How to run it

Run the application from client folder and specify current group from your config file or other params.

Example:

python tm_app.py -v=INFO -g=prod

Config encryption

python cryptorshell.py encryptdir Q:\dev\_projects\github\simple_timemachine\client\config Q:\dev\_projects\github\simple_timemachine\client\config\encrypted --pattern private* --pubkey simple_time_machine.pub.pem
