This article explains how to do consistent file-based backups for ploop containers, using ploop snapshot feature.
Assuming you have a running container identified by $CTID. The following needs to be done:
# Known snapshot ID
ID=$(uuidgen)
# Directory used to mount a snapshot
MNTDIR=./mnt
mkdir $MNTDIR
# Take a snapshot without suspending a CT and saving its config
vzctl snapshot $CTID --id $ID --skip-suspend --skip-config
# Mount the snapshot taken
vzctl snapshot-mount $CTID --id $ID --target $MNTDIR
# Perform a backup using your favorite backup tool
# (tar is just an example)
tar cf backup.tar.xz $MNTDIR
# Unmount the snapshot
vzctl snapshot-umount $CTID --id $ID
# Delete (merge) the snapshot
vzctl snapshot-delete $CTID --id $IDFor more information, see vzctl(8), section Snapshotting.
