We’ve decreased the amount of time it takes to back up sites on multi-core servers. Backups are compressed using gzip to decrease the time it takes to transfer a backup to the backup storage location and reduce required storage space.

Running gzip in parallel leverages the capabilities of multi-core servers by distributing the compression tasks across multiple processors, utilizing all available CPU cores. This considerably shortens the time needed to create backups. Between this and other backup improvements, we’ve reduced the total queue time per day from around 500 hours to under 200 hours!
