I recently produced few lines to this question as it sometime overlooked during a disk based backup solutions purchase phases. www.driftec.co.uk
As the choice of our disk backup solutions strongly rely on the below key factors.
1. Backup and recovery performance optimisation.
• The Recovery Time Objective (RTO).
• Determine the backup Window.
• Plan backup type (full, incremental and logs backup).
• Determine the data growth rate.
• Define the retention policy
Although the above are true, I believe the choice of disk backup technology today is more importantly down to how the appliance is handling the deduplication process as this can affect your DR plan.
the two leading deduplication technologies are inline and disk-based deduplication.
While inline deduplication is processed before the data reaching disks and will require more processing resources but is faster across WAN replication from one DR site to another.
Disks based deduplication instead will not require the same amount of processing resources and will back/and restore faster.
The two technologies mentioned above can affect your backup window and set wrong RTO expectation.
To complete your purchase decision, you should also consider your solution cost, implementation and your rate of data growth for future scale-out.
Find out what your peers are saying about Dell Technologies, Hewlett Packard Enterprise, ExaGrid and others in Disk Based Backup Systems. Updated: March 2024.
Disk-based backup systems represent a significant evolution in data protection strategies, offering a more flexible and faster alternative to traditional tape backups. These systems utilize hard disk drives (HDDs) or solid-state drives (SSDs) to store backup data, enabling quicker data recovery and improved reliability.

• CPU
• Storage capacity
• Internal buses
• Memory
