Proxmox VE备份策略

虚拟备份

#!/usr/bin/env bash
# 描述: Proxmox 虚拟机备份脚本,并实现自动清理

set -e

KEEPDAYS=3
NAME="snapshot-$(date +%Y-%m-%d_%H-%M-%S)"
BACKUP_DIR=/backup/dump

VMIDS=(
       100
       150
       151
       152
       153
       154
       200
       241
)

for VMID in ${VMIDS[@]}
do
    if ! vzdump --compress zstd $VMID --dumpdir ${BACKUP_DIR} --prune-backups keep-daily=${KEEPDAYS}; then
        logger -t "$(basename $0)" "[ ${VMID} ] backup status [ failed ]."
        exit 1
    fi
done

此时，在脚本定义备份好的VM，都会保留3份备份。
