Hi there,
I just discovered DietPi a few weeks ago and used this as an opportunity to learn some things about NAS / Cloud / Router Setups. It is really a great jumping off point for non-experts like me and the amount of work and skill put into it really shows. Thanks for that.
On Topic:
The Idea was to use a Raspberry 4 /4GB to replace my old Router, Synology NAS (mainly data storage + Plex) and to add Pihole to my Network.
So far, I was able to realize most of the things described above. One thing I am struggling with is the NAS part.
I have one 4 TB HDD (Seagate 2,5") attached to the USB 3.0 Port. Let´s call this one DRIVE A. I mounted it and use Samba Share to make it discover-able for the Clients in my Network (works).
Now I want to use a second DRIVE B, identical to DRIVE A to backup / sync the contents of DRIVE A, as soon as the Drive is physically connected to the Raspberry´s 2nd USB 3.0 port and to un-mount / spin down DRIVE B as soon as the job is finished.
I am looking for some guidance of how to archive the task above.
On a side note -
hdparam did not spin down the attached Seagate DRIVE A so I installed hd-idle via this tutorial which works fine.
Thanks for your tips and stay safe
Hi,
many thanks for your message. There isn’t such function build into DietPi. However you could have a look to the following guide.

Thank you for the link I will read into it!
Hi again,
I tried to follow the guide - unfortunately with no luck . When I connect the Backup Drive B, nothing happens.
Also I am not sure if I mounted the Drives correctly which might contribute to the guide not working.
Currently dietpi-drive_manager is configured as following:
Drive A: = Main Drive ext4
/dev/sda1/
/mnt/NAS/
Drive B: = Backup Drive ntfs - connecting this drive to USB should trigger automatic mounting, backup and unmount
/dev/sdb2/
/mnt/BACKUP/
I noticed, that when i umount Drive B it, disconnect it, and then re-connect it I manually have to mount it again and instead of /BACKUP it suggests the drives UUID as Mounting point.
Hi, Joulinar I want to add second 3TB HDD to my Dietpi serwer [Rpi4+HDD 3,5", 3TB connected with USB]. I’m also looking for solution to auto backup my whole data from first HDD. I never use RAID or other things like that. Can You tell me what is the best way? Does my Rpi4 handle two HDD’s [2x3TB, 3,5", USB with external power supply]?
Regards,
Przemko
yes your RPi is able to handle both HDD as separate volumes. If you like to do regular backps from HDD1 to HDD2, you could have a look to DietPi-Sync.
Joulinar Thanks I will do that.
