我在nutanix中创建了一个复制规则。我不明白一个话题。保留计划区域中远程办公室的最后一个快照。将其留空并选择1或3.我应该使用这个地方吗？此选项会创建返回点。

另一个问题是这个;我有一个细磁盘100 GB虚拟服务器。它在快照复制规则中占用空间。它有多少快照空间计算？

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>

你好 @dotex.

“保持最后一个快照”是在老化最古老之前保留流通的快照数量。例如，具有每小时计划的3个快照意味着过去3小时将有快照，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。

不确定是否正确地了解了第二个问题，假设您要查看该特定服务器的快照的大小。答案与任何平台都一样：发生的更改越多，快照的大小就越多。

基本上快照是一个存储块的跟踪器更改。它们而不是将它们覆盖到原始磁盘中，它们被写入快照文件，以便如果需要，可以恢复恢复。更改存储块越多，将越多的数据被写入快照文件。

例如，在SQL Server上的数据库（或记录或本地DB备份的合并）生成大量变化，因此快照的大小可以大幅生长。

请告诉我，如果有帮助。
