Sync 1.4.2 Release Notes

Product Release: July 8, 2013

Release Notes Updated: July 8, 2013

 WHAT’S NEW

This major release of Aspera Sync 1.4.2 provides many new capabilities and several important defect fixes.

•         A new de-duplication capability (“–dedup) allows async to identify file paths already in its snap database and create hardlinks at the destination (avoiding transfer and storage of files already at the destination).

•         New configurable maximum pending number allows for maximum parallelism and synchronization speed when de-duplication is high.

•         Include and exclude filters are now supported in continuous mode (in addition to one-time mode), and are implemented to avoid all unnecessary operations on excluded paths for fastest performance.

•         Cooloff interval is now configurable (for maximum performance).

•         On Windows, new capability skips files that would yield a sharing violation and retries these paths a configurable number of times.

•         async responds to cancel and rate control management and is fully manageable within Console 1.7 and higher.

•         async reports all per file and cumulative statistics to Console 1.7 and higher.

•         asyncadmin and async support automatic expiration of lock files fixing issues with lingering lock files

•         async is now available for Solaris, BSD 64-bit

•         async supports manifest file creation at the initiator and at the remote.

•         async supports automatic migration of the snapshot database

•         async has new options to set (force) the uid and gid on sync’d paths at the target

•         async checks hostname of the remote peer and ignores IP changes in the local endpoint, resolving issues with remote endpoint checking in environments with variable IPs

•         async has new option to specify the remote command executed

•         asyncadmin now reports files in conflict, syncd, and pending separately and reports the status of an individual file by file name; asyncadmin also supports new version command (-v)

•         many enhancements in async logging, including option to pass the log file size (“:NNNN”) before rotation and reports last run time, and time since last run

•         Performance and scalability improvements for async reporting (eliminating the slowdown that previously occurred at around 100,000 files).

•         Multiple bugs fixes (see FIXED ISSUES section)
