What is the best way to periodically backup folder from cache to array. Copy only new or changed files.

I know there is a plugin for backup Appdata folder but I have custom folder on Cache pool because I need performance but I also need protection so I want to make backup to array.

 

Is there a plugin or script to backup selected folders from cache to array?

rsync from a user script

I am still kinda new to Unraid. So just so I understand.

 

On my cache drive I make a share called home_dir. 

Then in user script I setup a rsync  

But do I need to make a 2th share on the array (home_dir_backup) to use as a target. 

Or should I use /mnt/disk2/home_dir as a destination ?

 

Making a extra share feels a bit redundant.

But declaring /mnt/disk# feels not good aswel

 

Would love to hear what Is considered the best practice.

You need a second share to avoid confusing behaviour!   Unraid only expects a file to be in one location.

Thank you for the super fast reply. I will setup a second backup_homedir share on the array and have Rsync do its magic
