Check the following factors are considered or not?

1.Database size and growth should be mentioned initially.

2.Check the unused index and drop the unused index.

Then set up your maintenance plan for backup,dbcc reindex,etc

50GB is not large. You should be able to handle it just like any other smaller DB.

Integrity check is a must for all DBs whether small or large.

With what error? Just saying it's failing isn't much use.

Maintenance:
Backups, full maybe diff, probably log depending on RPO and RTO requirements
Index maintenance
Integrity checks
Possible additional statistics maintenance
Test restores to ensure your backups are useful.
Alerts configured to tell you before things break

First, before I do anything on a new server I stand up a pre-determined utility database for DBA related activities. Maintenance jobs that I run but not limiting to are:

Clearing out aged backups
Creating backups for new databases that get dropped onto my server ( in my case all DB's are mission critical )
Cycle SQL Server Error Logs
Index Defrag
Smart Re-Indexing
Alerting on Extended Blocking

Again, these are my main chunks for maintenance but definitely not limiting what I have listed. You could have more, 50GB is not really that big. Should be able to get a good grasp on it.

Thanks,
Chris
