## Remote Server Backup Script
## Author: Ze'ev Schurmann
## Reddit: u/thisiszeev
## License: MIT
## Dependancies:
## ffprobe (ffmpeg), jq
## Please consider making me small donation. Even though my scripts are open source and free to use, I still need to eat. And the
## occasional bottle of wine also goes down well.
## $5 buys me a cup of coffee
## $10 buys me a nice burger
## $20 buys me a bottle of wine
## Anything above that will be awesome as well.
## You can send me a donation via Paypal https://www.paypal.com/paypalme/thisiszeev
## Drop me a message on Reddit if you do make a donation.
## Support is only offered freely to those who donate $20 or more.
## Your donation contributes to further development.
## If you need a custom script, contact me on Reddit for pricing.
