MySQL 定时数据备份的实现需要创建备份文件
<ol class="dp-xml"> <li class="alt"><span><span>if [ ! -d $BackupPath ]; then </span></span></li> <li><span>mkdir $BackupPath </span></li> <li class="alt"><span>fi </span></li> <li><span>echo "---------------------------" </span></li> <li class="alt"><span>echo $(date +"%y-%m-%d %H:%M:%S") </span></li> <li><span>echo "---------------------------" </span></li> </ol>
删除历史文件
<ol class="dp-xml"> <li class="alt"><span><span>if [ -f $OldFile ]; then </span></span></li> <li> <span>rm -f $OldFile </span><span class="tag">></span><span class="tag">></span><span> $LogFile </span> </li> <li class="alt"><span>echo "[$OldFile]Delete Old File Success!" </span></li> <li><span>else </span></li> <li class="alt"><span>echo "not exist old file!" </span></li> <li><span>fi </span></li> </ol>
新文件
<ol class="dp-xml"> <li class="alt"><span><span>if [ -f $NewFile ]; then </span></span></li> <li><span>echo "[$NewFile] The Backup File is exists,Can't Backup! " </span></li> <li class="alt"><span>else </span></li> <li>MySQL<span>dump -u $DBUser $DBName </span><span class="tag">></span><span> $DumpFile </span> </li> <li class="alt"><span>tar czvf $NewFile $DumpFile </span></li> <li><span>rm -rf $DumpFile </span></li> <li class="alt"><span>echo "[$NewFile]Backup Success!" </span></li> <li><span>fi </span></li> </ol>
