Effortless Data Backup with Duplicati and Docker: A Complete Installation Guide

[@hydrochloricgrip4464]

Thanks for the help in Discord and here as well!

Looks like you might be a Tube Archivist user? Would you consider making a video/series on that? There are very few of them on YT and I don't really understand why. It's a great app!

Thanks for this! I was thinking about using Rclone for this purpose, but it has no usable in-built webgui with scheduling at the moment. I could setup backing up my Home Assistant to Google Drive with Duplicati in a matter of minutes.

thank you very mcuh

Great video! How are you backing up the duplicati database that contains the information you need to restore in the event of a complete server rebuild? On a newly rebuilt server you will have an empty duplicati database.

Hey, reading the docs I was going based off this - “If you don't have an exported configuration file, you need to know the backend URL, credentials and the backup passphrase. Once entered all needed information, you can start restoring your files.” - duplicati.readthedocs.io/en/latest/03-using-the-graphical-user-interface/#restoring-files-if-your-duplicati-installation-is-lost

@@Techdox maybe Duplicate can backup it's own config directory :)

Well done

DUplicati never worked for me. I had always database problems and was not able to figure out the root cause.

[@askeladden450]

The cause is that you need to stop the containers before backing up the volumes. If a DB transaction is occuring during backup, your DB might get corrupted. Either stop the containers, or carry out backup when no one will be using the DB, or use the DB specific cli to dump the db data into a file and then backup that file. You would need a bash script for this.

[@alexneagoe5258]

what happens if the docker volumes or binds that you back up will have read / write ops when they are backed up? shouldn't the container be stoped before being backed up?

[@Techdox]

Yeah if it’s active data then you could have a cron job that stops the containers before the backup etc

[@ISBayHudson]

Interested to know if you looked at restic?

[@Techdox]

I've looked into it but have yet to actually use it. Might have a play later today. Do you use it?

[@ISBayHudson]

@@Techdox I've used it once to backup some stuff before a reinstall but considering some better backups for a bunch of stuff. When trying to decide between Duplicati and Restic there were a bunch of posts on reddit etc. talking about issues with Duplicati. Plan would be to backup to unraid server via Minio and rclone to MS Drive (6TB for $18 NZ/mth is the best deal I've found for cloud storage!) The restic UI (cli) is pretty nifty - havne't looked at any front end for it though.
