Hello.
I call the proxmox backup client from within a bash script - on a daily basis using cron. The computer I am backing up is a desktop PC with linux Mint. For an unknown reason, much of the data get transferred everytime the script runs - even if the data has not been altered. Please take a look at the example log:
Data within the mountpoint /home/katja/ has been preexisting and has not been altered. So why are only 1.3% MB reused? This happens similar for other mountspoints as well - in one of them, more than 100GB are transferred over and over again. The script already ran for several weeks on a daily basis.
PBS has been on Version 3.2.X until today. I just updated to version 3.4 - I will monitor if that should change anything.
Can you please tell me how to investigate this issue further?
Thank you in advance.
