A software and hardware facility persistently maintains metrics on directories at different levels within a tree of a filesystem. The facility hierarchically aggregates attributes of files contained by directories and stores them as metric values in each directory within a tree. The stored values represent summed or otherwise aggregated data from the descendant directories and files. The metric values represent aggregated attributes such as checksums, MIN and/or MAX aggregates, sameness bits, bloom filter aggregates, queryable user tags, moving average aggregates, b-tree aggregates, etc. The facility provides mechanisms for efficiently sampling activities performed by the filesystem and visually representing these activities.

Filesystem capacity and performance metrics and visualizations

A facility comprising methods and systems for analyzing and visualizing trends in the usage of data within a shared storage filesystem is disclosed. The facility analyzes the rate at which the filesystem or a portion thereof is used by periodically generating manifests of the usage of the filesystem and comparing one manifest to another manifest. Furthermore, the facility may store additional information relevant to the manifest, such as the time at which the manifest was taken; for each directory, the sum of all of the values determined for items in that directory (including any subdirectories); and so on. In this manner, the facility collects and stores information relevant to developing trend information for each item in the filesystem. The trends analysis and visualizations described herein provide quick insight into the changes deemed most interesting or significant between two times.

Analyzing and visualizing trends in the use and consumption of data in a shared storage system

A technology for automatically saving an original copy of an image file in a location hidden from a user is disclosed. The technology accesses metadata associated with an image file and determines whether an original copy of the image file exists. Provided an original copy of the image file exists, an edited version of the image file along with an identifier is saved. If an original copy of the image file does not exist, an original copy of the image file is created, the original copy of the image file is stored, and an edited version of the image file along with an identifier is saved.
