rsync

If you're using borg already, look at rsync.net https://www.rsync.net/products/borg.html

Specifically rsync -av which will archive, preserving the time stamps, and tell you what is being copied.

The script rsync's your local folder to the production folder I prefer #2 really as it's simpler and I don't need to go through GitHub ssh keys shenanigans when setting up on new servers.

I have my media backed up on a NAS that I’ll sync with rsync daily. The initial sync was long but after that it’s not bad.

rsync on a chron job from WSL will do the trick.

I use rsync scripts with the link-dest feature to create the versioned backups. Each backup looks like a full backup, but only new or modified files are actually copied. Files present in the previous backup are hardlinked from there. So it is like a sync, but it preserves previous states.

Rsync will create a new sync copy and any changes from previous running can be stored elsewhere.

Rsync is slower but it does more than cp especially around verifying that the files were copied correctly. You want this.

I use rsync. Let the initial backup run overnight and then incrementals after will be quick.

Every month, I make a copy of everything (I use RSYNC) onto a remote server to hold everything in case of emergency.
