Windows 7 备份 - 自动删除旧的备份范围

我有一个 1TB 的 USB 驱动器，我用它作为工作电脑的备份驱动器。

驱动器最终将耗尽空间，我需要进入并使用管理空间/查看备份对话框删除旧备份并删除过去时期的备份。

有没有什么方法可以告诉 Windows Backup 以更智能的方式管理备份空间并保留尽可能多的备份，但不会超出驱动器大小并发出错误？

答案1

我编写了这个脚本，每周运行一次：

wbadmin delete backup -keepversions:7 -quiet

简单，发射后就不管。

答案2

保留最新的 3 个备份：

wbadmin delete backup -keepversions:3 -quiet
  1. 打开记事本并输入以下行。
  2. 将文件保存为 remove-old-backups.bat
  3. 打开任务计划程序（Windows 10）
  4. 右键点击“创建任务”
  5. [常规]：填写描述
  6. [触发器] > [新建] > [按计划] > [每周] … （每周运行）
  7. [操作] > [新建] > [启动程序] > 选择您的 .bat 文件

这样就可以了。

命令信息：

wbadmin delete backup /?
wbadmin 1.0 - Backup command-line tool

ERROR - Command syntax incorrect. Error: /?. See the command
syntax below.

Syntax: WBADMIN DELETE BACKUP
  {-keepVersions:<No. of copies> | -version:<VersionIdentifier> | -deleteOldest}
  [-backupTarget:<VolumeName>]
  [-machine:<BackupMachineName>]
  [-quiet]

Description:  Deletes the backups that you specify. If the
specified volume contains backups other than backups of the local
server, those backups will not be deleted.
To use this command, you must be a member of the Backup Operators group
or Administrators group.

Parameters:
-keepVersions  Specifies the number of the latest backups to
                keep. The value must be a positive integer. The option value
                -keepVersions:0 deletes all the backups.

-version       Version identifier of the backup in MM/DD/YYYY-HH:MM format.
                If you do not know the version identifier, at a command
                prompt, type:  WBADMIN GET VERSIONS. Versions that are
                exclusively backups can be deleted using this
                command. Use WBADMIN GET ITEMS to view the version type.

-deleteOldest  Deletes the oldest backup.

-backupTarget  Specifies the storage location for the backup that you want
                to delete. The storage location for backups is a
                drive letter, a mount point, or a GUID-based volume path. This
                value only needs to be specified for locating backups that are
                not of the local computer. Information about backups for the
                local computer will be available in the backup catalog on the
                local computer.

-machine       Specifies the computer whose backup you want to
                delete. Useful when multiple computers were backed up to
                the same location. Should be used when -backupTarget is
                specified.

-quiet         Runs the command with no prompts to the user.

Remarks: One, and only one, of these parameters must be specified:
-keepVersions, -version, or -deleteOldest.

Examples:
WBADMIN DELETE BACKUP -version:03/31/2006-10:00
WBADMIN DELETE BACKUP -keepVersions:3
WBADMIN DELETE BACKUP -backupTarget:f: -deleteOldest

答案3

这有点老套，但答案是：不。Windows（7）备份不会自动删除旧备份，也没有（自动）执行此操作的能力。

如果您需要，则首选第三方备份工具。

答案4

Windows 7 备份不会自动删除旧备份。我写了一个简单的自动识别脚本查找最旧的备份目录，如果有 4 个或更多，则删除它。然后我将其添加为每天早上运行的计划任务。

这是脚本。
