Hi,
I know this is quite an old thread, but maybe somebody is still interested: We maintain a shell script to mirror local backups to encrypted USB drives (including auto-mount), see https://github.com/foundata/proxmox-pve_backup_usb.
Probably not for enterprise (where a Proxmox Backup Server should do its job), but an easy disaster backup layer for SOHO (and some enterprises on top, too; one never has enough backup )."
