Is the only option to run a REPAIR with ALLOW DATALOSS ? We have backups but this issue may have been occurring for a few weeks. Is there any other options ?

CHECKDB found 0 allocation errors and 33 consistency errors in table 'EXP_TRV' (object ID 174623665).
CHECKDB found 0 allocation errors and 44 consistency errors in database 'EXP_1'.
repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (NetPerfMon).

You can restore a clean backup (one from before the corruption occurred), or you can run checkDB with repair allow data loss and lose a whole bunch of data from the table EXP_TRV
I recommend the backup if at all possible.
Once fixed, do some root cause analysis, something caused this corruption, most likely something in the IO subsystem somewhere. Also revise and enhance your backup strategies.

SQL In The Wild: Discussions on DB performance with occasional diversions into recoverability
January 31, 2013 at 7:07 am
The EXP_TRV had a truncation run on it a few days before the error occurred. It was something suggested by our supplier, after The growth of the data in this table was queried. Could this have been the cause ? From the results is it only this table affected, if so is it possible just to run a repair on this table ? If I run a DBCC with data loss, is data loss only going to affect this table ?
January 31, 2013 at 7:15 am
Nope. Corruption is something outside of SQL mangling the database. Check your IO subsystem
You need to do a full DB repair, there's corruption not associated with an object as well. Should just be the table identified.
