The Total Required Disk Space is divided into the Staging Store and the Chunk Store. If you intend to use different file systems or disks for the Staging Store and the Chunk Store, it is important to know how much of the Total Required Disk Space is allocated to the Staging Store versus the Chunk Store. Use the following calculations to determine this amount.During the NetVault SmartDisk Deduplicated Backup process, backups are initially streamed to the Staging Store where they remain until the deduplication process is finished. The Staging Store must be large enough to hold all the backups while they await deduplication.If the deduplication window overlaps the backup window, deduplication and backups occur at the same time. Each backup starts deduplicating after the backup job is finished. Also, large backups are broken into 400 GB segments. Each segment starts to deduplicate after it is received, even if the backup stream is still being streamed to the Staging Store. Therefore, the Staging Store only requires space to hold some portion of the total backup size. If the Staging Store runs out of space, vRanger backups fail.
