环境

CentOS Linux release 7.9.2009 (Core)
Confluence 7.12.0
Jira 8.16.1

备份

由 cp -a 代替 rsync，在数据量很大时，rsync -a 经常出现上班时间仍未复制完成，仍在进行复制。
远端同步时挂载，同步后卸载 nfs。
未成功挂载 nfs 时，则不进行 复制 本地本地备份 到 远端操作（实际为本地），避免重复数据。
远端备份采用 rsync 同步，每次与最新版本地备份 local_latest 镜像。

本地备份删除

以保留最新数量的备份文件方式，删除多余备份文件；不以过期时间定义是否删除备份文件；避免未备份成功的情况下，备份文件仍被删除。
本地保留 4 份。

keep_num_latest_files.sh

#!/bin/bash
#Keep the latest number of files.
 
KEEP_NUM=4
DEL_DATE=`date +'%Y%m%d'`
WORK_PATH=/backup/local
LOG_PATH=/backup/log
LOG_FILE_NAME=delete.log
LOG=${LOG_PATH}/${LOG_FILE_NAME}
 
if [ ! -d ${WORK_PATH} ];then
    mkdir -p ${WORK_PATH}
fi
if [ ! -d ${LOG_PATH} ];then
    mkdir -p ${LOG_PATH}
fi
 
echo -e '\n\n' >> ${LOG}
echo ${DEL_DATE} >> ${LOG}
 
cd ${WORK_PATH}
echo "The following files in the working path will be deleted:\n" >> ${LOG}
ls -1tr | head -n -${KEEP_NUM} | grep -v "${LOG_FILE_NAME}" >> ${LOG}
ls -1tr | head -n -${KEEP_NUM} | grep -v "${LOG_FILE_NAME}" | xargs -d '\n' rm -rf &> /dev/null

远程 本地备份

最新备份：/data/jira_wiki_backup/
上次备份：/data/jira_wiki_backup_old/

remote_local_backup.sh

#!/bin/bash
#远程备份后 远程机器本地备份 两份备份。
 
SRC_PATH=/data/jira_wiki_backup
DST_PATH=/data/jira_wiki_backup_old
RSYNC_LOG=/data/rsync.log
rsync -av --ignore-existing --delete ${SRC_PATH}/  ${DST_PATH}/ &>> ${RSYNC_LOG}
