dirty-bitmap

Do you need to shutdown VMs to backup them with stop mode? Or is it needlessly loosing uptime by doing so? Here is how I used to think it works: I thought it does not matter if the VM is running or not. In both cases the VM will be shutdown, a complete backup taken, during that the VM will be...

Hallo zusammen Mein System: kleines PVE-Cluster im Rechenzentrum erstes PBS Backup auf PBS und Speicher vom RZ zweites Backup auf meinen lokalen PBS mit smb-Storage auf NAS Gedanklicher Hintergrund: PBS-Storage im RZ hat eine sehr schnelle Anbindung an meine PVE-Server und kann dadurch schnell...

Hi all, We have a bunch of VMs that we back up twice a day, to 2 different destinations: once to PBS and once to NFS. I had expected the dirty-bitmap to become invalid because of the alternating backup destinations, but apparently, that's not an issue because one uses vzdump and the other PBS...

Hello All, Hope this email finds you well. I have been trying with proxmox for a while now, and have come across a problem specific to dirty bitmaps. I have enabled bitmap on the qcow2 disk image using 'qemu-img bitmap' command, exposed the bitmap over a unix socket using 'qemu-nbd' command...

Hi, I know this has been discussed a bit in a previous thread, such as: https://forum.proxmox.com/threads/dirty-new-bitmaps.81754/page-3 but I wanted to see if there has been any movement in the opinion of allowing administrators to force bitmap persistence on stopped VMs. As Krzysztof...

I'm currently scripting a process involving the creation of a disk bitmap using QMP commands. Initially, the bitmap count is set at 131072. However, after adding or modifying data on the disk, the count doesn't increase. To troubleshoot this issue, I conducted a similar process with the VM...

Hello, We are really happy with PBS! Back-up is much faster and we can hold more retention with the incremental/deduplcation function. We have a dedicated PBS server with 12 x 8TB disk en 2 x Enterprise SSD for special device. We currently have set special_small_blocks to 4K, is this the right...

Dear Proxmox community members, first A HUGE THANK for absolutely amazing tools, including PBS. Testing it on two places already some weeks and after understanding the retention setting I say it is a life saver. I am down from 4 hrs to 1 hr with daily virtual machines backups. Amazing...
