Multiple volume image backup issue on Server 2.5.22

11

So far everything runs very smooth, I’m very happy with my adjustments :slight_smile:

In addition to that I just wanted to share a small script I will run at startup to clean up the files after a reboot (I haven’t setup datto to reload the snapshots before mounting the drives yet). This should get rid of any obsolete .datto, .overlay or cbt_info files at startup:

#!/bin/sh

for FILE in /mnt/urbackup_snaps/cbt_info/*-cowfile
do
    SNAP_COWFILE_PATH=$(cat $FILE)
    SNAP_COWFILE_NAME=".$(cat $FILE | cut -d '.' -f2-)"
    if [ ! -e /proc/datto-info ] || ! grep -q "$SNAP_COWFILE_NAME" /proc/datto-info; then
        echo "COW-File is not loaded by kernel module"
        if [ -e $SNAP_COWFILE_PATH ]; then
            echo "Deleting $SNAP_COWFILE_PATH"
            rm -f $SNAP_COWFILE_PATH
        fi
        DEVNUM_PATH=$(echo "$FILE" | sed s/-cowfile$/-snapdev/)
        if [ -e $DEVNUM_PATH ]; then
            echo "Deleting $DEVNUM_PATH"
            rm -f $DEVNUM_PATH
        fi
        OVERLAY_PATH=$(echo "$SNAP_COWFILE_PATH" | sed s/.datto_3d41c58e-6724-4d47-8981-11c766a08a24/.overlay_2fefd007-3e48-4162-b2c6-45ccdda22f37/)
        if [ -e $OVERLAY_PATH ]; then
            echo "Deleting $OVERLAY_PATH"
            rm -f $OVERLAY_PATH
        fi
        echo "Deleting $FILE"
        rm -f $FILE
    fi
done
