    Tape backup is very slow

    I just tried the tape backup of the Proxmox Backup server, but the transfer speed is very slow. (Max 60 MB/s) I also use the same tape with Bareos and there I found out that setting the tape block size to 1 MB made a sigificant performance improvment. (From under 100 MB/s to over 300 MB/s) Is...

    i want to use tape backup without a changer. For a small installation ( complete backup fits on one tape ) i want to create something with minimal user interaction.
