Yes, you can run a separate verify job, again & again. I am assuming htat this job has run multiple times before without error? If the verify fails multiple times, then I would assume the backup is bad and I would re-run the backup. If the verify passes, then it might have just been a momentary glitch during hte first verify.
I’m verifying as you said but I get the error which is depicted in the Picture.How can I handle with this?And also the errors are not only in jobs with problem but in all jobs.
There was an issue with running manual verify in BE 2014. Would recommend to ensure BE 2014 is patched up with SP2 and run a verify along with the backup job itself.
