我在nutanix中创建了一个复制规则。我一个话题都不懂。将远程办公的最后快照保存在“时间表”区域。留空，选择1或3。我应该在哪种情况下使用这个地方?这个选项创建了我的返回点。

另一个问题是;我有一个100gb的精简磁盘虚拟服务器。占用快照复制规则的空间。它需要计算多少快照空间?

谢谢

Hi @Dotex<\/user-mention>\u00a0<\/p>

\u201cKeep the last snapshots\u201d is the number of snapshots to retain in circulation before ageing the oldest. For example, 3 snapshots with an hourly schedule would mean that there would be snapshots for the past 3 hours and when the fourth snapshot is taken the first one would be aged and merged to the baseline.<\/p>

Not sure if I understand your second question correctly, Assuming that you\u2019re looking to estimate the size of the snapshot of that particular server. The answer is the same as with any platform really: the more changes take place the more the size of the snapshot is.<\/p>

Essentially snapshot is a tracker of storage block changes. Instead of overwriting them into the original disk, they are written to the snapshot file so that if required a recovery is possible. The more storage blocks are changed, the more data is written to the snapshot file.<\/p>

For example, a rebuild of the database on an SQL server (or merging of logs or local DB backup) generate a lot of changes hence the size of the snapshot can grow substantially.<\/p>

Let me know if that helps, please.<\/p>","className":"post__content__best_answer"}">

I created a replication rule in nutanix. I did not understand a topic. keep the last snapshots for remote office in Schedule area. Leave it blank and choose 1 or 3. For which scenario should I use this place? this option creates my return point.<\/p>

Another question is this; I have a thin disk 100 gb virtual server. It takes up space in the snapshot replication rule. How much snapshot space does it have a calculation for?<\/p>

thanks<\/p>

嗨 @Dotex

“保留最后的快照”是指在最老的快照变老之前保留在循环中的快照数量。例如，每小时有3个快照，这意味着过去3个小时会有快照，当第四个快照被拍摄时，第一个快照将被老化并合并到基线。

不确定我是否正确地理解了你的第二个问题，假设你想要估计特定服务器快照的大小。答案其实与任何平台一样:更改越多，快照的大小就越大。

快照本质上是存储块更改的跟踪器。不是将它们覆盖到原始磁盘，而是将它们写入快照文件，以便在需要时进行恢复。修改的存储块越多，写入快照文件的数据就越多。

例如，在SQL服务器上重建数据库(或合并日志或本地DB备份)会产生大量更改，因此快照的大小可能会大幅增加。

如果有帮助，请告诉我。
