VMware CBT based Incremental Backup

BDRSuite’s VMware CBT based Incremental Backup feature provides a powerful and efficient solution for backing up virtual machines.

CBT (Changed Block Tracking) technology is used to identify and track the changes made to a virtual machine’s disk since the last backup, allowing for faster and more efficient incremental backups.

BDRSuite backs up only the modified blocks of a virtual disk rather than backing up an entire disk for each incremental backup job. This saves more storage space, and time and lowers the bandwidth utilization from being over-consumed through incremental backup jobs.

Key Benefits

Faster Backup

CBT technology helps reduce the time it takes to backup virtual machines, allowing you to complete backup quickly and easily.

Reduced Storage Requirements

By only backing up the changed blocks of a virtual machine, CBT based Incremental Backup reduces the amount of storage space required to save backups.

Improved Recovery Time

With faster backup times, CBT based Incremental Backup makes it easier and quicker to recover from data loss.

Reliable Data Protection

BDRSuite’s CBT based Incremental Backup feature provides reliable and efficient data protection, giving you peace of mind knowing your data is secure.

How it Works

BDRSuite’s CBT can easily track the Disk-specific block changes and performs block-level backup/replication for the incremental job.

• BDRSuite auto-enables CBT for a virtual machine when a backup/replication job is scheduled
• The first backup of a virtual machine is a full backup, and during the full backup/replication schedule, the used block information of configured VM will be saved as a reference file which defines the current state of VM disks
• Subsequent backups are incremental backups and during the incremental process, the reference file will be used to identify the changed blocks from the previous backup/replication, then the changed blocks alone will be backed up/replicated to the backup server
• The current disk state will be updated to the reference file during each incremental schedule, to assist the next incremental job
• Backups are stored in a secure and easily accessible location, allowing for quick and efficient recovery in the event of data loss
