To Backup a LVM 1000GB VM , SMlog showing the rquired storage is more than 900GB.BTW , I'm trying to take backup in a external NAS storage using continuous replication

Can you please suggest any work around to backup the VM.

@sumansahabd
Its an LVM-repository. To replicate, you need a snapshot first. A snapshot needs at least 2x the size of the volume on the repository.

Please check, if this is really the case. If you have a VHD which consumes 51% of the SR, you are not able to snapshot/replicate.

It's more work, but...

you have to stop the VM and export them,
delete the current SR (Local Storage),
recreate SR (Local Storage) as local ext4 format
import the VM back

In this way you switch from LVM to ext4 and the space it needs will be small, not double the space
