No release date announced, but first patch serie is 1year old, so I think it should be ready "soon" (< 6month)

Hi Alexandre, 

is there any release date (RC,...?) of qemu's incremental backups scheduled? 

Thanks + regards,

I think the main problem is that a full backup is done on qemu side (all 
block are reads), 
but it's piped to xdelta to generate the diff file. 


The coming qemu incremental backup allow to really read only the changed 
block since the last backup.

Hi, 
Please, may you send the link to the thread in wich it is explained the 
reason for which the Ayufan's patch is not suitable? 

It seems that the Ayufan's patch integrates well in the Proxmox web 
interface and it allows management of differential backs from it. 

We need something like this because we have several customers with 
disaster recovery systems in remote data centers and copying full 
backups takes lot of bandwidth and time. 

Best regards.
