SQL 2008 R2 Database. Backup failed with this message:
BACKUP 'Db' detected an error on page (1:24909497) in file 'D:\Data\Db.mdf'.
Msg 3013, Level 16, State 1, Server xxxxx, Line 1
BACKUP DATABASE is terminating abnormally.

I ran DBCC CHECKDB on the database which came back without any errors.

The backup ran successfully after that and the next day too.
I looked at the page with DBCC PAGE - each time I ran it gave a different output. sometimes more sometimes less.
msdb..suspect_pages has 2 entries for event type 1 and 2.

What would I look for particularly on the output to check for corruption?

What would be the next steps to make sure everything is good?
Thanks!

Anything like an index rebuild occur between the backup and the checkDB?
