Question

我正在为我正在设置的sharepoint服务器创建备份策略。

每天都有备份。

从长远来看，我想保留：

* Daily backups for the last week.
* Weekly backups for the last month.
* Monthly backups for the last year.
* Yearly backups.

如果我用bash / cygwin编写，我会发现写一个脚本来清除这个策略不需要的备份相当容易。但是我宁愿不必安装cygwin，我宁愿使用本机DOS脚本或其他专业工具。

我的DOS脚本技巧非常原始，所以我想知道是否有其他人有类似的脚本/工具我可以使用。

干杯！

Answer 1

您可以使用PowerShell来实现相当强制的备份过程。或者您可以用 Python 或其他可执行脚本语言编写脚本。

PowerShell最初可以进行复杂处理，但它基本上是批处理脚本 on crack ，可以访问.NET运行时。

注意：PowerShell我相信只能在2003年，Vista，Windows 7上使用（我知道它附带它们，至少，可能可以使用XP / 2000，但我不是当然）。 Python可以安装在任何东西上。

我最终编写了一个bash脚本来执行此操作。 run-backup-maintenance.sh

用法示例：run-backup-maintenance.sh d7w4m12y10 / cygdrive / d / backup“。*。tar”

注意：所有每日备份必须写入：/ cygdrive / d / backup / daily

如果使用参数d7w4m12y10运行，此脚本会确保随着时间的推移：

/cygdrive/d/backup/daily    will contain daily backups for the last 7 days
/cygdrive/d/backup/weekly   will contain weekly backups for the last 4 weeks
/cygdrive/d/backup/monthly  will contain monthly backups for the last 12 months
/cygdrive/d/backup/yearly   will contain yearly backups for the last 10 years

享受！

脚本或util用于删除旧备份
