正如跟进,以下是我所做的代码。 Mjolinor的建议使用简化的(相对而言)CSV文件的解决方案极大(感谢您)的。我当然试图让解决方案太复杂。
我创造了我用来驱动过程中的三个CSV文件中。首先是RotateBackups_Masterlist.txt文件。 BackupName是备份的名称,因为它在后续过程中与之关联。 VersionsRetained是要保持的数字。 BackupType是它是文件还是文件夹备份。
RowNbr,BackupName,VersionsRetained,BackupType
1,TargetBackup,2,Folder
2,LstDefBackup,5,File
3,XMLBackup,3,File
4,SourceBackup,2,Folder
5,TXTBackup,8,File
第二个文件是RotateBackups_FolderList.txt。 BackupName对应于上述文件中的相同字段,Foldername是要备份的文件夹。
RowNbr,BackupName,FolderName
1,TargetBackup,c:\MyBooks\target
2,SourceBackup,c:\MyBooks\source
第三个文件是RotateBackups_FileExtensions.txt。 BackupName对应于第一个文件中的相同字段,FileExtension是要备份的文件的通配名称(它也将接受模式),而FolderLoc是要找到这些项目的文件夹。
RowNbr,BackupName,FileExtension,FolderLoc
1,LstDefBackup,*.def,c:\MyBooks\target
2,LstDefBackup,*.lst,c:\MyBooks\target
3,XMLBackup,*.xml,c:\MyBooks\target
4,TXTBackup,*.txt,c:\MyBooks\rfiles
请注意,相同的文件扩展名可以备份到多个备份名。此外,可以将多个文件夹分配给相同的BackupName和FileExtension。
作用:
- 它的文件名创建与它的zip文件,这些文件的 BackupName场(主文件)的名字命名加上日期时间戳(所有 同一批次内)的文件夹。
- 这些文件名都具有相同的BATCH日期时间戳,因此您将 知道以20120401_091500.zip结尾的所有备份均为 ,这些备份都是在同一次运行中创建的。
- 它使您能够进行版本备份,并为您提供 时间点来恢复。
- 它使您在管理备份空间 需求方面有一定的灵活性。它使您能够针对关键备份保留较长的保留时间 ,或者对较不重要的备份保留较短的保留时间。
- 删除的项目可以被破坏性删除或回收。
- 根据创建日期,您的备份不会老化。导致备份被标记为删除的唯一的 是新建的 ,它将计数放在要保留的数字上。
它不会做什么:
- 我没有很多的错误在它的处理,比检查 空数组或LASTEXITCODE之前立即删除文件等。
- 这并不意味着同一类型的文件的庞大的数字是 备份使用的文件扩展名,如备份是一个-AT-A-时间 函数调用创建/更新一个zip文件。
最后,该做的工作的代码(张贴在全部意见后)。我从很多来源获取了许多部分代码,并感谢他们每个人的原始海报/开发人员。使用此实用程序需要您自担风险。我欢迎其他人可能希望补充的任何改进。
这是创建备份的功能。
function create-7zip([String] $aDirectory, [String] $aZipfile){
[string]$pathToZipExe = "C:\Program Files\7-zip\7z.exe";
[Array]$arguments = "a", "-tzip", "$aZipfile", "$aDirectory", "-r";
& $pathToZipExe $arguments;
}
# Call it by using:
#create-7zip "c:\temp\myFolder" "c:\temp\myFolder.zip"
变量&数组初始化这里,从上面的文本文件都在这里进口。变量$ KillOrRecycle设置为回收站,所以删除的任何内容都会回收站。杀死是一个破坏性的,不可恢复的文件删除。

$myDocFolder = "c:\Documents and Settings\MyPC\My Documents\"
# Import text files for master, folder and file backup information
$bkupRotateMasterArr = Import-Csv $myDocFolder"RotateBackups_MasterList.txt"
$fldrBkupArray = Import-Csv $myDocFolder"RotateBackups_FolderList.txt"
$fileExtBkupArr = Import-Csv $myDocFolder"RotateBackups_FileExtensions.txt"
# Switch to delete Item or to send to recycle bin
# delete is destructive and cannot recover file.
# Recycle setting removes file from folder, but sends to recycle bin
# and can be restored if needed.
# Must be either "Kill" or "Recycle"
$KillOrRecycle = "Recycle"
#************************************************************************************
#************************************************************************************
装入导入的CSV文件的内容为哈希表。
$ bkup_Counts是BackupName的散列表&要保留的文件数。
$ bkupTypeArr是BackupNames的阵列(稍后使用)
$ fArray是BackupName的散列表和文件名生成一个与它相关联。
$ nameConv在顶部完成,为此运行中的所有文件提供相同的日期时间戳。
# Load contents of master backup array
$bkup_Counts = @{}
$b = $null
foreach($b in $bkupRotateMasterArr)
{
$bkup_Counts[$b.BackupName] = $b.VersionsRetained
}
#set Backup Types from the array we just defined
$type = $null
foreach ($type in $bkup_Counts.Keys) {
$bkupTypeArr += $type
}
#create array of our filenames for this batch
$type = $null
$fArray = @{}
foreach ($type in $bkupRotateMasterArr) {
$fArray[$type.BackupName] = ($type.BackupName + $nameConv)
}
接下来,如果我们有fileExtension阵列中的任何数据,通过它使用的文件夹位置&文件扩展名运行(递归)抓住一切事情,从路径匹配它,它与适当的BackupName关联。这增加了$文件列表中的哈希表具有FullName属性为关键,并作为值与相关联的BackupName。
# if extension array not null, get list of files to back up
if ($fileExtBkupArr) {
# Gather the list of files to be backed up
$f = $null
foreach ($f in $fileExtBkupArr) {
$arr = @()
$arr = (Get-ChildItem $f.FolderLoc -Recurse -Include $f.FileExtension | Select-Object fullname)
foreach ($a in $arr) {
if ($a) {
$fileList[$a] = $f.BackupName
} # if $a not null
} # end inner foreach
} # end outer foreach
} # if FileExtension Backup Array not null
然后,如果filelist散列表上有任何内容,请将其压缩到适当命名的备份。
# if filelist count gt zero, then create zip file of them for appropriate backup
if ($fileList.Count -gt 0) { # must have entries in hashtable
$f = $null
#Loop thru file list & associate file with the appropriate backup
foreach ($f in $fileList.Keys) {
$arcFile = $null
if ($fileList.ContainsKey($f)) {
if ($fArray.ContainsKey($fileList[$f])) {
$arcFile = $fArray[$fileList[$f]]
create-7zip $f.FullName $zipFolder\$arcFile
} #if key in fArray
} # if key in Filelist
} # end foreach
} # if hastable not empty
接下来,如果我们有要备份的文件夹,然后使用类似的过程来使用类似的方法备份这些文件夹。
# if folder backup not null then back up folders
if ($fldrBkupArray) { # check if array not null (no entries)
$f = $null
#Backup Folders now
foreach ($f in $fldrBkupArray) {
$arcFldr = $null
#if ($fArray.ContainsKey($f[1])) {
if ($fArray.ContainsKey($f.BackupName)) {
$arcFldr = $fArray[$f.BackupName]
create-7zip $f.FolderName $zipFolder\$arcFldr
} #end if
} # end foreach
} # end if $fldrBkupArray not null
下一项是要确保我们在删除任何东西之前没有失败。我们根据归档位是否设置来删除,并将删除的文件发送到回收站(默认)或位桶。
# if 7zip succeeded, we'll continue
if ($LASTEXITCODE -gt 0)
{Throw "7Zip failed" }
ELSE { # if Exitcode = 0 then continue with job
# Remove any files with Archive bit = False
# we marked it for deletion in previous run
Add-Type -AssemblyName Microsoft.VisualBasic
$files=get-childitem -path $zipFolder
# we'll delete all files that don't have the archive bit set
Foreach($file in $files) {
If((Get-ItemProperty -Path $file.fullname).attributes -band [io.fileattributes]::archive)
{ Write-output "$file is set to be retained" }
ELSE {
if ($KillOrRecycle = "Recycle") {
Write-output "$file does not have the archive bit set. Deleting (Sent to recycle bin)."
[Microsoft.VisualBasic.FileIO.Filesystem]::DeleteFile($file.fullname,'OnlyErrorDialogs','SendToRecycleBin')
$output = $_.ErrorDetails
}
ELSE {
Write-output "$file does not have the archive bit set. Deleting."
remove-item -recurse $file.fullname
$output =$_.ErrorDetails
}
}
} #end Foreach
接下来,BackupName &计数导出到一个XML文件,在存档文件夹计数的文件(通过BackupName型),然后设置上的所有文件的存档位,所以我们可以标记多余的人删除。
# Export BackupCounts to XML
$bkup_counts | Export-Clixml bkup_counts.xml
# Get Number of ZIP files in folder
$btype = $null
foreach ($btype in $bkupTypeArr) {
$FileCountArray += ,@(($btype),(dir $zipFolder\$btype"*.zip").count)
}
# Import BkupCounts from XML
$bkup_Counts= Import-Clixml bkup_counts.xml
# set Attribute byte on ALL files in zipfolder so we know we'll get the right ones
attrib $zipFolder"\*" +a
现在,回到通的bkup_Counts哈希表,从文件数的计数得到BackupName模式匹配的文件数,并减去保留的天。如果差异大于0,那么我们必须从该文件夹中删除那么多条目。
我们通过使用相同的图案BackupName管道的文件夹,在创建时间属性排序,然后选择第一N个文件,其中N是上面的保留值大于零的数目。
然后,对于我们选择的每个对象,请返回&将存档位设置为FALSE以将其标记为在下次运行时删除。
$row = $null
# Get LST & DEF filenames in array & display count
foreach ($row in $bkup_Counts.Keys) {
Get-ChildItem -Path $zipFolder -Include $row"*" -Recurse #|
(dir $zipFolder\$row"*".zip).count - $bkup_Counts[$row]
$delfiles = 0
$delfiles = (dir $zipFolder\$row"*".zip).count - $bkup_Counts[$row]
if ($delfiles -gt 0) { #sort folder by createdtime
# if more than specified nbr of backups present, un-archive excess ones to delete next run.
dir $zipFolder\$row"*" | sort-object -property {$_.CreationTime} |
select-object -first $delfiles |
foreach-object { attrib $_.FULLNAME -A}
} # end if delfiles gt 0
} # End foreach in bkup_counts
} # End Else Last ExitCode = 0

最初,我做到了。 XML中的结构和命名约定并不是很丰富,我不认为它们可以定制,或者至少不容易。 – 2012-03-29 16:35:01
看你的数据,我不能说我看到任何一个XML格式提供您不能使用.csv文件获取,这将是更容易处理脚本的内外。恕我直言。 – mjolinor 2012-03-29 17:15:41
我甚至没有考虑过 - 你是110%正确的。感谢您提出我未曾考虑的明显解决方案。 – 2012-03-29 18:13:11
