Your occasional cloud and tape storage round-up

Our round up starts with an on-premises tape backup replacement, meanders through storage in the cloud, and returns to tape with a new LTFS indexing scheme that saves space and time.

We finish with DataCore’s exec roster revamp and InfiniteIO and Nasuni hires

Cohesity backsup a fire service

On-premises tape backup systems are still being replaced with disk-based ones. Cohesity customer West Midlands Fire Service has replaced tape backup and an 11-mile weekly tape trip to an offsite DR centre with Cohesity’s backup.

A server backup now takes five minutes, saving the service over 360 hours a year – the equivalent of almost 2.5 months of time for a full-time engineer. Critical data is backed up hourly and global variable length deduplication provided on-premises and cloud storage savings.

HYCU goes in for cloud lifting and shifting

HYCU offers backup and recovery of Virtual Machines in Nutanix environments. Protégé is a new HYCU data protection offering for hybrid and public clouds.

It provides a mechanism to “lift and shift” customer applications from one cloud to another, making sure the data is protected throughout. A single-click feature enables customers to recover specific applications onto a different cloud for test and dev, and a disaster recovery option across clouds is available

HYCU wrote in a blog that “what customers want us to do here is to automate the entire process and make it a one-click operation to migrate an entire application from on-prem or Cloud to another Cloud.” HYCU Protégé will simplify the process to become a one-click migration.

Protégé should be generally available in the third 2019  quarter.

IDC on public cloud spending

IDC forecasts worldwide spending on public cloud services and infrastructure will more than double from $229bn in 2019 to nearly $500bn in 2023. This represents a five-year compound annual growth rate (CAGR) of 22.3 per cent.

SaaS will be the largest revenue category, followed by PaaS and then IaaS.

IaaS spending, comprised of servers and storage devices, will be the fastest growing category of cloud spending with a five-year CAGR of 32 per cent, compared to the PaaS CAGR of 29.9 per cent. IDC has not publicly revealed the SaaS CAGR.

IaaS spending will represent more than 40 per cent of public cloud services spending by the professional services industry in 2023, compared to less than 30 per cent for most other industries. Professional services will also see the fastest growth in public cloud spending with a five-year CAGR of 25.6 per cent

LTFS gets indexing taped

The Linear Tape File System, which presents a file:folder interface to LTO tapes, has a new, more efficient file indexing scheme. It comes from the SNIA Linear Tape File System (LTFS) Technical Work Group (TWG.)

LTFS stores files and their metadata on the same tape and makes the data accessible through the file system interface. The LTFS standard defines the data recording structure on the tape and the metadata format in XML. It creates a full index when new files are added.

V2.5 of the LTFS format specification uses a new and incremental indexing method with a journal-like capability where only changes to the index need to be recorded frequently. A complete index is required to be written at unmount time.

Incremental indexing reduces the tape space needed for the index data so more data can be written to the tape, and also reduces the index writing time. Both are particularly helpful when small files are written to the tape. The LTFS people have IOT sensors generating small files of data which can now be written more efficiently to tape.

A reference implementation of LTFS format version 2.4 is available as open source at GitHub project here. Presumably v2.5’s ISO base media file format will appear on Github shortly; its current status is: ”not started yet.”
