SUMMARY
A detailed explanation of what the verify backups option does when creating a job
ISSUE
What is the verify backup option when creating a backup job?
RESOLUTION
Inline Backup Verification is a method to ensure data sent during backup has been properly received.
The verify backup option is a checksum calculation that runs on the source client sending us the data. The target appliance is equally calculating a checksum of received data. .
Both of these are compared at job end in the backup summary, and if they do not match, the job is failed.
In a local LAN, it is extremely rare for a block to both successfully be received by a NIC, and also be corrupt, but, for those rare potential cases, this would catch that condition.
