Using the Aspera Watch Service with Sync

Sync can use asperawatchd for more efficient file system change detection, particularly for file systems with many files.

Starting Aspera Watch Services and Creating Watches
The Aspera Watch Service (asperawatchd) is a file system change detection and snapshot service that is optimized for speed, scale, and distributed sources. On file systems that have file system notifications, changes in source file systems (new files and directories, deleted items, and renames) are detected immediately, eliminating the need to scan the file system. On file systems without file notifications, such as object storage, Solaris, and AIX file system scans are automatically triggered.
Starting the Aspera Watch Service
Sync can be configured to use asperawatchd for fast synchronization of very large numbers of files without scanning the directory. Synccan push files from a local directory, pull files from a remote directory, or create a bi-directional session between two directories (as long as asperawatchd is properly configured to monitor both directories).
Watch Service Configuration
The Aspera Watch Service configuration in the <server> section of aspera.conf includes the snapshot database, snapshot frequency, and logging:
