Embodiments are directed to managing data in a file system over a network. A file system that includes objects may be provided. A capacity value of the file system may be provided based on a storage size of the objects. A threshold value may be determined based on the capacity value and a metric partition count. Traversals of the file system may determine metric partitions such that each metric partition may be associated with some objects Metrics associated with activities that are associated with the file system may be monitored. Metric partition values may be determined based on metric values associated with the metric partitions such that each metric partition value may be based on a portion of the metric values associated with a portion of the activities associated with a corresponding metric partition. Visualizations may be generated based on the metric partition values.

User interfaces for managing distributed file systems

Embodiments are directed to a replication engine that provides a root node for a file that may be associated with a replication snapshot where the file is comprised of the root node, internal nodes, and data nodes. The replication engine may start at the root node and traverse the file system. If a visited internal node has an epoch value that matches the epoch, the replication engine may continue the traversal by visiting a next unvisited adjacent internal node. If the visited internal node has an epoch value that mismatches the epoch, the replication engine may backtrack to a nearest adjacent internal node that matches the epoch. And, in response to visiting a data node the replication engine may be arranged to determine blocks that are associated with the data node and communicate a copy of the blocks to a target file system.

Data replication in distributed file systems

Embodiments are directed to a file system engine that provides a file system with parent objects associated with child objects. The file system engine provides a replication snapshot associated with an epoch of the file system such that each child object modified during the epoch and each associated parent object is associated with the replication snapshot. A root object of a portion of the file system included in the replication snapshot may be provided. A replication engine may traverse the portion of file system starting from the root object such that the parent objects that are not associated with the replication snapshot are omitted from the traversal. The replication engine may determine replication objects based on the traversal such that each replication object was modified during the epoch. Then the replication engine may execute a replication job that copies replication objects to a target file system.

Replicating file system objects in distributed file systems

Embodiments are directed to file systems. A replication engine may establish a secure communication channel between a source file system and a target file system. The replication engine may: instantiate a replication job associated with rules; determine changes in the source file system; determine characteristics of the replication job that may be based on the changes; compare the to the characteristics and a black-out schedule; execute the replication job to communicate the changes in the source file system to the target file system based on a result of the comparison. Upon completion of the replication job, the replication engine may automatically instantiating a next replication job to copy subsequent changes in the source file system to the target file system.
