使用带有祖父父子脚本的NFS装载脚本，但只能获得每日6次的备份。 我还应该有4个每周和2个月的备份

我正在使用rsync克隆从远程服务器（MT DV4.0）到本地（Ubuntu 11.10）的变化。 然后我使用下面的复制/粘贴脚本来压缩然后存档文件。

#!/bin/bash #################################### # # Backup to NFS mount script with # grandfather-father-son rotation. # #################################### # What to backup. backup_files="/home/server-backups/var/www/vhosts /home/server-backups/var/www/vhosts" # Where to backup to. dest="/home/bryan/server-tar" # Setup variables for the archive filename. day=$(date +%A) hostname=$(hostname -s) # Find which week of the month 1-4 it is. day_num=$(date +%d) if (( $day_num <= 7 )); then week_file="$hostname-week1.tgz" elif (( $day_num > 7 && $day_num <= 14 )); then week_file="$hostname-week2.tgz" elif (( $day_num > 14 && $day_num <= 21 )); then week_file="$hostname-week3.tgz" elif (( $day_num > 21 && $day_num < 32 )); then week_file="$hostname-week4.tgz" fi # Find if the Month is odd or even. month_num=$(date +%m) month=$(expr $month_num % 2) if [ $month -eq 0 ]; then month_file="$hostname-month2.tgz" else month_file="$hostname-month1.tgz" fi # Create archive filename. if [ $day_num == 1 ]; then archive_file=$month_file elif [ $day != "Saturday" ]; then archive_file="$hostname-$day.tgz" else archive_file=$week_file fi # Print start status message. echo "Backing up $backup_files to $dest/$archive_file" date echo # Backup the files using tar. tar czf $dest/$archive_file $backup_files # Print end status message. echo echo "Backup finished" date # Long listing of files in $dest to check file sizes. ls -lh $dest/ 

每日备份似乎工作得很好，但我只得到6每日备份。 星期六不见了（这应该是每周备份运行的那一天）。 每月的备份也不见了。

我是服务器pipe理业余人员，所以任何帮助将不胜感激。 谢谢！

• 哪个SBS 2008文件值得支持最高级别的冗余？
• Tarball备份导致大量服务器滞后
• 在CentOS Linux上运行的服务器上卸载硬盘后进入睡眠状态？
• 系统磁盘备份映像的最佳方式是什么？
• Exchange 2010 SP1裸机恢复将无法启动EMC
