Pure Storage has filed a patent for a method that monitors the usage of a source volume and uses this information to prioritize the restoration of backup extents to a restore volume. The method involves accessing a usage map associated with the backup volume, prioritizing the backup extents based on usage metrics, and copying them to the restore volume accordingly. This technology aims to improve the efficiency of data restoration processes. GlobalData’s report on Pure Storage gives a 360-degree view of the company including its patenting strategy.

Method for prioritizing and copying backup extents to a restore volume
A recently filed patent (Publication Number: US20230315586A1) describes a method and system for creating a restore volume from a backup volume. The method involves accessing a usage map associated with the backup volume, which contains usage metrics indicating the usage of source extents in the source volume. Based on these metrics, the backup extents are prioritized for copying from the backup volume to the restore volume. The restore volume is essentially a duplicate copy of the backup volume.
The patent also includes a method for generating the usage map. This involves monitoring operations directed to the source extents of the source volume before backing up the source volume to the backup volume. Each time an operation is detected, the usage metric associated with the corresponding source extent is updated.
Additionally, the patent describes bringing the restore volume online before all the backup extents are copied from the backup volume. This can be achieved by mounting the restore volume when a certain threshold is met. The usage of the source extents includes both reads from and writes to the source extents.
The patent also includes a system comprising one or more processors and storage. The system is capable of detecting reads or writes to source extents in a source volume and updating usage statistics associated with the source extents accordingly. The system can generate a restore volume from a backup of the source volume based on the usage statistics, copying the backup extents to the restore volume in a specific order determined by the statistics.
The patent further discusses the usage statistics, which can include a count of accesses to the source extents, a rate of accesses, or a usage score. These statistics form a histogram of the usage of the source extents.
The patent also mentions the possibility of mounting the restore volume before it is fully restored from the backup. The timing of mounting the restore volume can be determined based on factors such as the number of backup extents copied, the amount of data copied, or the usage statistics.
Overall, this patent presents a method and system for efficiently creating a restore volume from a backup volume, prioritizing the copying of backup extents based on usage metrics, and potentially bringing the restore volume online before the full restoration is complete.
