We were seeing our backup growing quite quickly almost every day
On Thursday of last week, we had an autogrowth event and soon after the size of our backup decreased significantly.
I ran DBCC SQLPERF(logspace) and got the following result
Here is a snapshot of the last few backups
The autogrowth event happened before the 3/20 backup but nothing changed. Then we had a huge decrease the following day,with the decrease coming from the log file. What would be the cause of this?
