BR脚本备份数据至远程主机
#2

有备份到远程电脑和删除历史备份的方案不、？

#3

与远程存储备份的机器配置上互信，如下是否可行

########## #rm 3 days ago bak ############

cd $BAK_BASE
find $BAK_BASE -mtime +3 -type d -exec rm -rf {} ;

#scp $BAK_BASE/$BAK_FILENAME.tar.gz backup@****:/home/backup

#ssh backup@****:/home/backup 'echo “--------------delete *.zip --------------”;

cd /home/backup;

find /home/backup -mtime +7 -name “*.tar.gz” -exec rm -r {} ;’

#4

脚本很好
