How to download a backup file

Support
1

I’m running Netheserver 7.9.2009 with backups going to a USB-connected hard drive under control of Duplicity. I am concerned that the hardware is showing signs of age and want to clone my system onto new hardware. How can I download the latest backup file off the USB disk, so that I can use it on another build, without having to unmount/remove/power down anything?

Thanks

Jim

To install NS7 on another hardware you need to get the config backup file backup-config.tar.xz and the most recent full backup named like duplicity-full.20251101T231520Z.vol*.difftar.gz and the most recent incremental backup named like duplicity-inc.20251101T231520Z.vol*.difftar.gz

Hi Markus, Thanks for responding. I have the config file, thats no problem, it downloads to a PC, but its the duplicity files I don’t know how to download so I can re-upload them to new hardware. I don’t really want to power off or disconnect anything, the tin may fail, so I’l like to download it to a PC so I can put it on some other (USB?) media for use on new tin

It’s not possible to download the data backup files like the config backup file, you’d need to copy the data backup files from the USB disk.

EDIT:

Another way would be to create another data backup schedule to for example a NAS.

Is it safe/possible and if so how, to unmount the USB media and then remount it after copying files off it for use in a different system?

The USB disk is only mounted during the backup so it should be safe to unplug it, when the backup is not running.
When the next scheduled backup starts, the USB disk is going to be remounted.

Perfect, so because my backup runs at 02:00 in the morning, I can disconnect it and reconnect it at will….if I understand you correctly. Thanks for your help, Kudos to you!
