This article will explain in detail what the SQL Server information about PlateSpin backup is like. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

When PlateSpin makes DR backups at the server level, the SQL Server log contains the information of "I was resumed on database xxx O is frozen on database xxxx" and "I was resumed on database xxx".

In fact, later found that when the PlateSpin job runs, you will find that the database will record a full backup of the database to Virtual Device in msdb.dbo.backupset. This is also a side evidence! Of course, more detailed, more in-depth aspects of the principle, knowledge points, due to the online PlateSpine information is not much, I do not have time to in-depth understanding. This is just a detail I found when I was collecting backup information. I wondered at that time that I didn't have a full backup or backup to a virtual device (Virtual Device) at that point. After looking for the reason, I found that this had something to do with PlateSpin. Here is a record!
