The document discusses the challenges and solutions of implementing a 3-2-1 backup strategy using hybrid cloud storage. It highlights the inefficiencies of traditional backups and presents primary cloud storage as a superior alternative that simplifies disaster recovery and reduces costs. ClearSky's solution offers multi-cloud access with lifecycle data protection, making it beneficial for industries like healthcare, finance, and legal services.

3. Can Primary Storage + Cloud Replace Backups?

4. 3-2-1 A
Standard To
Measure By
● Three copies of data
● Two different types of
Media
● At least one copy off-site

5. ● Data is copied to from primary to a secondary storage
system (both primary and secondary need to be bought and managed)
● Data is replicated or shipped to a disaster recovery site
(storage in secondary site and the site itself must be managed)
● Data is stored on either tape or in the cloud to meet the two
different types of media requirement
● In most cases stored data is not immediately addressable. It has
to be restored to be used
Meeting 3-2-1 with Backups

6. ● Basics of 3-2-1 are met but
○ Backups are infrequent, typically
once per day
○ Recoveries are slow, data needs
to be transformed before used
Problems Meeting 3-2-1 with Backup Storage

7. Meeting 3-2-1 with Primary
Storage (no cloud)
● Data is snapshot for point-in-time recovery
● Data is replicated from primary storage
system to a secondary primary storage
system (not a secondary storage system)
● Data is replicated from primary storage
system to a remote primary storage
system (not a secondary storage system)

8. Problems
Meeting 3-2-1
with Primary
Storage
(no cloud)
● There is no “2” - exact same
storage system throughout
● Really expensive

9. ● First the Architecture
○ Compute / Applications remain
on-premises
○ All-Flash cache on-premises
○ Second tier at regional cloud
provider
○ Third tier at large cloud provider
Meeting 3-2-1 with Primary Storage on Cloud
● All-Flash Solves Performance
○ Regional Tier solves latency
○ Large cloud solves durability

10. Meeting 3-2-1 with Primary Storage on Cloud
● New / modified data is written to cache and milliseconds later written
to regional tier, eventually (within minutes) replicated to large cloud
● Large cloud snapshots data and replicates to another region
● Exceeds copy requirement and off-site requirement without backup
infrastructure costs (backup software, backup servers, secondary storage)
● Two copies requirement met - data on multiple types of storage and
one of the large cloud copies can be set to read only, or have update
write limited

11. Advantages
● Cost Effective (eliminates
redundant primary storage,
eliminates backup infrastructure)
● Simple - IT deals with native data
not data stored in a backup
format
● Empowers cloud migration

12. Primary Storage on
Cloud Simplifies DR
● Data is already in cloud - no
additional transfers needed
● Data is already in a cloud
accessible format
● Start Primary storage on cloud
instance and direct compute
towards data
● Recovery in minutes without
upfront investments

13. Summary
● Using 3-2-1 as the Bar
○ Backup meets the requirement but does
so with data and recovery compromises
○ Primary storage meets “3” and “1” but
can’t deliver 2. Also is VERY expensive
○ Primary storage on cloud exceeds “3-2-
1”, improves protection quality and
reduces cost significantly
