Orange Whale

Orange whale is a backup software that uses telegram as free storge. A docker image is available, just mount the folders you want to backup and pass the folder names to LOCATIONS to tell Orange Whale what to upload.

It requires you to also mount /app/pub.txt, a file containing your public PGP key. Yes it is required, and yes it is useful. DO NOT upload your personal data on external services without encrypting them. Now the following envvar:

• TELOXIDE_TOKEN: is the token of the telegram bot you'll be using
• CHAT_ID: the group/channel your bot will upload to
• LOCATIONS: the folders to upload
• INTERVAL: an integer indicating how often to backup specified in hours
• RUST_LOG: logging verbosity. If you're using docker I advise you to set it to info

Warning

The key has to have only a single UID otherwise the program won't be able to encrypt. This is an issue of a dependency this program uses.

Backups

Once the bot starts uploading you'll realize that the data is split in multiple parts. That's because bots on telegram have an upload limit of 50MB on files. Just download all the parts and cat them together. After that you can decrypt using your PGP key and unpack using tar.

cat part_* | gpg -d | tar x
