Backup entire hard drive with proxmox-backup-client , integrity of the data

[Dark26]

I have a question . i backup a file sytem hardrice with proxmox-backup-client

/usr/bin/proxmox-backup-client backup Disque_system.img:/dev/vda

Does the proxmox-client doing a "freeze" for the disk-access during the backup like with the qemu agent in the VM ?

For example, if we have a database running on the server, a lots of data can be written during the time the disk is backuping, and the "database file" can be inconsistent on the backup.

Do you have some information about the process of backup an entire disk ?

Thanks

no, if you use the client manually you have to take care about consistency yourself (e.g. using snapshots of the underlying filesystems, export a db dump before the backup, etc.)
