## 前言 ##

Qlik sense的script log是非常多的,需要定期清理,所以本程序用的是powershell进行编写,功能如下:

*  `复制`半年前的日志(`.AddDays(-180)`可以修改具体的时间)到Temp文件夹
 *  用7Zip`压缩`日志文件夹并保存为`.zip`
 *  `删除`已经备份好的半年前日志文件

> \-`Copy` the log from half year ago (in `.AddDays(-180)` can modify the specific time) to the Temp folder  
> \-Use 7Zip to `compress` the log folder and save it as `.zip`  
> \-`Delete` the log files that has been backed up

## Power Script ##

Please find the below code:请参考以下代码:

echo " _ __ __ ___ "
    echo " | | | \/ | | \ "
    echo " | |__ | |\/| | | |) | "
    echo " |____| |_| |_| |___/ "
    echo "-------------------------"
    echo "ScriptLog HalfYear Backup"
    echo "by zhengkai.blog.csdn.net"
    echo "-------------------------"
    
    #get the current time string , nowTime is for naming the file/folder ,nowTime2 for putputing to file as last backup time
    [String]$nowTime = (Get-Date).ToString("yyyyMMddHHmmss")
    [String]$lastBackupTime = (Get-Date).AddDays(-180).ToString("yyyy-MM-dd HH:mm:ss")
    echo "TODAY=$($nowTime) HALFYEAR=$($lastBackupTime)"
    
    #the 7z execution application,7z.exe for silent mode,7zG.exe for UI mode,can see the process bar
    [String]$zip = "D:\Backups\app\7z.exe"
    
    #the folder to incremental backup
    [String]$sourcePath = "C:\ProgramData\Qlik\Sense\Log\Script\" #the path to save backup compression file when incremental backup completed [String]$destinationPath = "D:\Backups\ScriptLog\" #define backup file name with the current time string [String]$name = "$($destinationPath)\backup_$($nowTime).zip" #temp folder that will save the files and then backup ,will be deleted at the end [String]$temp = "$($destinationPath)\$($nowTime)" #or using tmp folder "$($env:TMP)\$((Get-Date).ToString("yyyyMMddHHmmss"))" if ($?) { #create if not exists temp folder if (!(Test-Path -Path $temp)) { New-Item -ItemType Directory -Path $temp } #created if not exists destination folder if (!(Test-Path -Path $destinationPath)) { New-Item -ItemType Directory -Path $destinationPath } #foreach the files and filter the items that the last write time equal than lastBackupTime Get-ChildItem -Path $sourcePath -Recurse -ErrorAction SilentlyContinue -include *.log | Where-Object -FilterScript {($_.LastWriteTime -lt $lastBackupTime)} | Copy-Item -Destination $temp -Force ECHO "Backup Done......" Get-ChildItem -Path $sourcePath -Recurse -ErrorAction SilentlyContinue -include *.log | Where-Object -FilterScript {($_.LastWriteTime -lt $lastBackupTime)} | Remove-item ECHO "Deletion Done......" } #start to zip temp folder and then save to destination Path & $zip a $name $temp ECHO "Compression Done......" #stop 5 seconds and then delete the temp folder Start-Sleep -s 5 Remove-Item $temp -Recurse ECHO "Remove Temp Done......" echo "-------------------------" echo "Backup SUCCESS!"
