What is All-Flash Tiered Backup?
Tiered All-Flash Backup is a storage architecture that uses different grades of flash memory for data protection. The "performance tier" allows for near-instant restoration of critical systems after a cyberattack, while the "capacity tier" uses high-density flash (like QLC) to store massive amounts of historical data more efficiently than traditional tape or disk.
My Take on Tiered All-Flash Backups
Even with high levels of compression and deduplication, an All-Flash solution for backup1 is a rare use case for enterprise storage. In the extreme case, these are probably restricted to critical VMs or databases that will impact business operations if one or the other fail.
Critical systems often can be backed to tiered storage that uses NVME or SSD as cache backed by slower devices such as HDDs or Tape2.
