Purpose
Understand how IDrive BMR ensures the reliability of the backed up data, for restore.
Description
The IDrive BMR device runs various checks through the backup operation to ensure that only reliable copies of data are stored during backup.
Backup integrity check for physical machines
The IDrive BMR device performs a three-tier check through the backup operation:
- Firstly, a block-by-block checksum verification before and after data transmission.
- Secondly, a built-in error correction mechanism that verifies data before writing it on the device.
- And finally, after the backup is completed, a filesystem mount check is executed to verify the availability of the data needed for a successful restore. The status of this final check is displayed in the IDrive BMR device UI and also notified to email addresses specified in the Backup Report Notification section.
Backup integrity status of physical machines
To check the backup integrity of the latest backup for a physical machine, go to Dashboard > Physical Machines > Clients and check the Integrity Status column.
The integrity status displayed for a group informs you of the backup integrity of the last backup in the group.
