Yes I bet its the run away query. The log sizes are 90 and 85 GB. the data file sizes are. 1.4 TB and 900 GB.

the delta run job might have caused the issue.

what can be done here. I'm unable to change the DB to FULL and take a FULL Backup.

What Am I supposed to do to create some space on disk. I need like 70 GB space on disk so that I can increase the log file space and CDC Job will do the rest.

Please suggest...
