The acronym NDMP shows up once in a while in NAS (Network Attached Storage) upgrade tenders. And for the less informed, NDMP (Network Data Management Protocol) was one of the early NAS data management (more like data mover specifications) initiatives to backup NAS devices, especially the NAS appliances that run proprietary operating systems code.
Backup software vendors often have agents developed specifically for an operating system or an operating environment. But back in the mid-1990s, 2000s, the internal file structures of these proprietary vendors were less exposed, making it harder for backup vendors to develop agents for them. Furthermore, there was a need to simplify the data movements of NAS files between backup servers and the NAS as a client, to the media servers and eventually to the tape or disk targets. The dominant network at the time ran at 100Mbits/sec.
To overcome this, Network Appliance® and PDC Solutions/Legato® developed the NDMP protocol, allowing proprietary NAS devices to run a standardized client-server architecture with the NDMP server daemon in the NAS and the backup service running as an NDMP client. Here is a simplified look at the NDMP architecture.
Blitzscaling has been on my mind a lot. Ever since I discovered that word a while back, it has returned time and time again to fill my thoughts. In the wake of COVID-19, and in the mire of this devastating pandemic, isblitzscaling still the right strategy for this generation of storage technology, hyperconverged, data management and cloud storage startups?
Blitzscaling is about hyper growing, scaling ultra fast and rocketing to escape velocity, at the expense of things like management efficiency, financial prudence, profits and others. While this blog focuses on storage companies, blitzscaling is probably most recognizable in the massive expansion of Uber (and contraction) a few years ago. In the US, the ride hailing war is between Uber and Lyft, but over here in South East Asia, just a few years back, it was between Uber and Grab. In China it was Uber and Didi.
From the storage angle, 2 segments exemplified the blitzscaling culture between 2015 and 2020.
Early in the year, I wrote about NAS systems being a high impact target for ransomware. I called NAS a goldmine for ransomware. This is still very true because NAS systems are the workhorses of many organizations. They serve files and folders and from it, the sharing and collaboration of Work.
Another common function for NAS systems is being a target for backups. In small medium organizations, backup software often direct their backups to a network drive in the network. Even for larger enterprise customers too, NAS is the common destination for backups.

Ransomware is obviously targeting the backup as another high impact target, with the potential to disrupt the rescue and the restoration of the work files and folders.
