Guys,

I recently compressed the folders where we store backups, as suggested here: http://www.databasejournal.com/features/mssql/article.php/3064361. Once I did it, however, the backup time increased from 1 hour to 5 hours.

Can anyone tell me whether this is normal and if there is a way to avoid this?


Thanks a lot!

Yes, it will be slower because the CPU has to compress a lot of data!
Let the backup application compress the data, not the Windows Server.

What backup application?

Are you referring to some 3rd party tool?

Yes, like Quest's litespeed or Idera's backup tool.
