BackupFile is being used by another process

[hubs984]

when i was backup database (database is very big ,about 13G ),it sometimes happen the following error,
when i set the ExportProgressChanged interval from 1min to 5min, This phenomenon has decreased,but sometimes also happen
do you know this reason?
tips: when the database is small,it never happens.

error stack trace:
System.IO.IOException: The process cannot access the file 'E:\MybackupPath xxxxxxxxxxxx\Mysql_useless_20250107184401.sql'

I have not encounter this problem before. I will later create a another test specifically to target very large database, such as 13G (in your case) or maybe 20G.

I'll come back to you later on this. At the mean time, feel free to explore the newly released v2.6.2, which has a lot of fixes, optimizations/improvements and new features.

I'll see you around
