Typical Backup Storage Requirements 11/25/2017 3:56 PM Typical Backup Storage Requirements Scalability Backup size + Horizontal expandability Performance Backup performance (backup window and RPO) + Restore performance (RTO) Cost Disk space consumption by backup archive + Hardware costs Integrity Ensure consistency + Detect silent data corruption Reliability Recover from data corruption © 2014 Microsoft Corporation.

Backup Size ReFS is built to scale 11/25/2017 3:56 PM Backup Size ReFS is built to scale The file system for the following decade (or two) 64-bit file system > most limits are 2^64 That is 18 billions billions of objects, or 16 EB data size (16,384 PB) No nasty NTFS limitations 64TB chkdsk volume limit of NTFS, max file fragments issues (FORMAT /L for 4096 FileRecords) © 2014 Microsoft Corporation. All rights reserved. MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

Horizontal Expandability 11/25/2017 3:56 PM Horizontal Expandability Core feature of Storage Spaces Simple expansion [up to a few nodes] with classic Storage Spaces Storage Spaces Direct make it easy to go up to 16 nodes (but requires Datacenter licensing) 4PB maximum storage pool size But unlimited pools in the system (and unlimited number of spaces in pool) © 2014 Microsoft Corporation.

Backup Window Write performance Write I/O test 11/25/2017 3:56 PM Backup Window Write performance ReFS is perfect for fat and slow hard drives because it behaves like log-structured file system when data integrity streams are enabled, eliminating I/O blender effect Write I/O test How 100% 4KB random writes land to the disk © 2014 Microsoft Corporation. All rights reserved. MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

Restore Performance Read performance Read I/O test 11/25/2017 3:56 PM Restore Performance Read performance ReFS is perfect for fat and slow hard drives because it was built to optimize reads via allocation and defrag policies (and again, enabling data integrity streams makes it even better for slow storage) Read I/O test How 100% random address requests land on the disk Perfect for running VMs directly from backup files! © 2014 Microsoft Corporation.

Backup File Management 11/25/2017 3:56 PM Backup File Management Accelerated full backup file transformations BlockClone API allows to create and modify files without actually moving data blocks around Up to 20x times faster performance By the way – the same API is used by Hyper-V 2016 to commit snapshots on ReFS © 2014 Microsoft Corporation.

Cost Hardware costs The case of missing ReFS dedupe? 11/25/2017 3:56 PM Cost Hardware costs General purpose servers and JBODs – enough said The case of missing ReFS dedupe? Pluggable architecture allows integrating software dedupe, which brings some unique benefits Disk space consumption by backup archive Raw disk space consumption by GFS backup archive rivals that of deduplicating storage appliances!

Integrity Prevents data corruption Detects silent corruption 11/25/2017 3:56 PM Integrity Prevents data corruption ReFS ensures consistency with allocate-on-write, so that data blocks are never modified in-place. Enabled by default for metadata, and for file data with data integrity stream enabled. Detects silent corruption ReFS data integrity scanner detects and notifies you about silent data corruption aka “bit rot” © 2014 Microsoft Corporation. All rights reserved.
