I amended this script to do a recursive look at all datasets in a given parent. For me I just need the purge function so I have commented out the snapshot part for my purposes: #!/bin/bash #v0.9.1 ########################simple-snapshot-zfs####################### ###################### User Defined Options ###################### # List your ZFS datasets. You can add/remove sets # readarray -t DATASETS < <(zfs list -o name -H) # when replacing DATASETS below, should return all pools/Datasets, not thoroughly tested yet. If you test this let me know! DATASET=("zfsbackup/cachebackup") mapfile -t DATASETS < <(zfs list -r -o name -H "${DATASET}") # Set Number of Snapshots to Keep SHANPSHOT_QTY=24 # Snapshot Name Format SNAPSHOTNAME=$(date "+simplesnap_%Y-%m-%d-%H:%M:%S") ###### Don't change below unless you know what you're doing ###### ################################################################## echo "Starting Snapshot ${SNAPSHOTNAME}" echo "_____________________________________________________________" ## Validation Steps # Validate SHANPSHOT_QTY if ! [[ $SHANPSHOT_QTY =~ ^[0-9]+$ ]]; then echo "Error: SHANPSHOT_QTY must be a positive integer." exit 1 fi # Validate DATASETS for dataset in "${DATASETS[@]}"; do if ! zfs list "$dataset" &>/dev/null; then echo "Error: Dataset '$dataset' does not exist." exit 1 fi done # Function to handle errors handle_error() { local error_message="$1" echo "Error: $error_message" exit 1 } # Function to create snapshot if there is changed data create_snapshot_if_changed() { local DATASET="$1" local WRITTEN WRITTEN=$(zfs get -H -o value written "${DATASET}") if [[ "${WRITTEN}" != "0" ]]; then if ! zfs snapshot "${DATASET}@${SNAPSHOTNAME}"; then handle_error "Failed to create snapshot for ${DATASET}" fi echo "Snapshot created: ${DATASET}@${SNAPSHOTNAME}" else echo "No changes detected in ${DATASET}. No snapshot created." fi } # Function to prune snapshots prune_snapshots() { local DATASET="$1" local KEEP="${SHANPSHOT_QTY}" # Declare the SNAPSHOTS array declare -a SNAPSHOTS # Use mapfile to split the output into the SNAPSHOTS array if ! mapfile -t SNAPSHOTS < <(zfs list -t snapshot -o name -s creation -r "${DATASET}" | grep "^${DATASET}@"); then echo "Error: Failed to list snapshots for ${DATASET}" return 1 fi local SNAPSHOTS_COUNT=${#SNAPSHOTS[@]} echo "Total snapshots for ${DATASET}: ${SNAPSHOTS_COUNT}" local SNAPSHOTS_SPACE if ! SNAPSHOTS_SPACE=$(zfs get -H -o value usedbysnapshots "${DATASET}"); then echo "Error: Failed to get space used by snapshots for ${DATASET}" return 1 fi echo "Space used by snapshots for ${DATASET}: ${SNAPSHOTS_SPACE}" if [[ ${SNAPSHOTS_COUNT} -gt ${KEEP} ]]; then local TO_DELETE=$((SNAPSHOTS_COUNT - KEEP)) for i in "${SNAPSHOTS[@]:0:${TO_DELETE}}"; do if ! zfs destroy "${i}"; then echo "Error: Failed to delete snapshot: ${i}" return 1 fi echo "Deleted snapshot: ${i}" echo "_____________________________________________________________" done else echo "_____________________________________________________________" fi } # Iterate over each dataset and call the functions for dataset in "${DATASETS[@]}"; do # create_snapshot_if_changed "${dataset}" prune_snapshots "${dataset}" done echo "----------------------------Done!----------------------------" Hope this helps someone.

No other containers are stopping, average RAM I can see is max 1GB for this container, overall memory is 20GB free. I can't see any obvious reason for the shutdown.

Thank you for the image. I am running this on unraid and have found all the versions are exiting with code 143 after a certain amount of hours (not sure how long yet). I can't find anything wrong though, no errors or issues. Any ideas?
