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!

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!
