VE Backup to multiple USB drives

[jona]

Hi all.
I'm currently using the backup mechanism of VE to backup my containers and vms to a NAS and to my Proxmox backup server.
I was wondering if there is a (simple) way to also backup to a pool of USB connected drives.
In detail this means, that I could have, let's say 5, USB drives and every day I only change the USB drive which is connected to the server. Without any UI interaction or anything else. Just unplug, and plug.
I have seen some posts about registering external devices, but nothing compared to this scenario.
Is there a way to handle backup devces like this?

Thanks and warm greeetings from spain.

A setup like this is going to wear out your USB ports with daily connect/disconnect.

SABRENT 36W 7 Port USB 3.0 Hub with Individual Power Switches and LEDs Includes 36W 12V/3A Power Adapter (HB-BUP7)

Keep your life simple, don't rely on USB and/or reduce the number of smaller drives to just a couple of larger drives that can handle a complete backup.

You already have a NAS, usb is secondary/tertiary - and while convenient, it's not the greatest for reliability.

@Kingneutron thank you very much for response. The tool looks quite interessting to me.
This is indeed a problem, but the intention is to always have an off-site backup.
Network shares are always connected, so a ransomeware attack would also make the backups on network drives useless. Another reason for having the additional off-site backups are robbery, fire, water, etc.

What would you use instead of USB drives as a secondary backup medium?

Hi, I found a post which tells how to backup Proxmox VMs to USB drive here: https://www.vinchin.com/vm-backup/proxmox-backup-vm-to-usb-drive.html
Hope this could help you.

Understandable. Look into ZFS snapshots for ransomware protection, and you can also duplicate them on another server (or cloud, such as rsync.net ) - IMHO it's best to keep ~30 days or less worth of snapshots on your primary server

You could also look into LTO tape drives, Proxmox Backup Server has support for tape
