Hi,

I have a 4.5GB database that takes about 67sec to restore and 30sec to backup.
Since it has a lot of unicode fields and the app doesn't support it, i decided to change them o ASCII, and NTEXT/TEXT to VARCHAR(MAX), and VARCHAR(<=3) to CHAR(#).
I generated the structure script and changed the fields, crated a new database and then I copied the data.
The new database still uses 3GB but to restore only takes 20sec as does the backup...
Is the normal? The same data, just less 33% space but 70% faster on restore...
The backups are compressed, the original is 900MB and the ASCII is 700MB..
I get 64MB/s on the original and 150MB/s on the new one from the disks...

Thanks,
Pedro

After lots of backups and restores the times are equivalent now...
Strange why it happened on the first place....
Does any one know?
The backup file fragmented or the database files?!?

Thanks,
Pedro
