Have you checked the error log? What information captured in it? Is this production server? Have you executed DBCC CHECKDB?

You haven't updated error from sql error log?

Can you restore with command line?

BACKUP DATABASE <DBNAME> TO DISK = '<PATH>'

Use backup log with TRUNCATE_ONLY option to truncate the log entries from .ldf file and run a full backup. It should work. But I would really recommend to have your I/O subsystem checked once with people who are responsible to manage this...

What does the error log say?

Oooh, a sharepoint content database...

Switch the database into simple recovery, checkpoint, checkpoint, checkpoint, (and a few more just to be sure), switch the DB back to full recovery and take a full backup, then you should be able to resume both full and log backups without error.

Then get the storage people to have a look at the IO subsystem for problems.
