Problem
The backup/replication/backup copy/recovery job fails with the following error.
Data size mismatch error has occurred while backing up/replicating/recovering/copying one or more disks/virtual disks/EBS volumes of the "X" VM/physical machine/backup/instance.
Background
The error occurs due to a mismatch in the expected data size to be processed and the actual size of the processed data which may result in a VM crash, data loss, etc.
Possible Cause
The error is most likely to occur in an unstable network environment when a full block of data gets lost during transmission.
Solution
To solve the problem, do the following:
- Make sure the network settings are configured correctly.
- Additionally, consider increasing the bandwidth limit to improve the connection speed.
