Backup and Snapshot of Proxmox

In my journey managing my Proxmox VE environment, I have constantly faced the critical task of data backups. In the past, I used Proxmox Backup Server, but soon realized that this solution had its downsides: it required the use of a dedicated PC and did not always guarantee the desired reliability and efficiency. Seeking a more integrated and reliable approach, I discovered a method that has proven to be much more advantageous: using snapshots directly on Proxmox VE with the transfer of backups to a TrueNAS VM.
