Hello i read scripts on openvz.org/Ploop/Backup
Quote:

vzctl snapshot $CTID --id $ID --skip-suspend --skip-config

# Perform a backup using your favorite backup tool
# (cp is just an example)
cp $VE_PRIVATE/root.hdd/* $BACKUPPATH/

# Delete (merge) the snapshot
vzctl snapshot-delete $CTID --id $ID

Why merge run after cp? Also, i can copy only root.hdd, without snapshot if snapshot already merged and deleted?

You don't want to keep a snapshot running after the copy because it creates a large amount of overhead for the filesystem.

Merging it basically closes out the snapshot. You merge all the changes made while the snapshot was open.
