TimeFinder SnapVX dramatically decreases the impact of snapshots and clones: l For snapshots, this is done by using redirect on write technology (ROW). l For clones, this is done by storing changed tracks (deltas) directly in the Storage Resource Pool of the source device - sharing tracks between snapshot versions and also with the source device, where possible.

Targetless snapshots TimeFinder SnapVX management interfaces enable you to take a snapshot of an entire VMAX3 Storage Group with a single command. With this in mind, VMAX3 supports up to 16K storage groups, which is enough even in the most demanding environment for one per application. The storage group construct already exists in the majority of cases as they are created for masking views.

Frequently Asked Questions about TimeFinder SnapVX This document addresses the most commonly asked questions about Dell EMC TimeFinder SnapVX software on PowerMax, VMAX All Flash, and VMAX3 storage arrays. TimeFinder SnapVX, usually just called SnapVX, was introduced with the DMX3. SnapVX uses Redirect-On-Write (ROW) technology, which is new to TimeFinder. When an update is made to a source track, this update is asynchronously written to a new location in the SRP, and the original data is preserved for the snapshot. Re: Use timefinder snapVX to copy a device BTW I should mention that you can use device files with SnapVX as well, but personally I like -devs better. The format of the device file will be different for establishing snapshots (source device) and linking targets (source and target pair).
