DataKeeper for Windows All Documentation - SIOS

CompressionOnce unlocked, the target volume is completely accessible. When finished inspecting the target volume, besure to continue the mirror to re-lock the target volume and allow DataKeeper to resync any changes thatoccurred on the source volume while the mirror was paused. Any writes made to the target volume while itwas unlocked will be lost when the mirror is continued.WARNING: If a reboot is performed on the target system while the target volume is unlocked, a full resyncwill occur when the target system comes back up.CompressionDataKeeper allows the user to choose the compression level associated with each mirror. Enablingcompression can result in improved replication performance, especially across slower networks. Acompression level setting of 3-5 represents a good balance between CPU usage and network efficiencybased on the system, network and workload.Note: The compression level of a mirror can be changed after the mirror is created. See the topic "Changingthe Compression Level of an Existing Mirror".Bandwidth ThrottleDataKeeper attempts to utilize all of the available network bandwidth. If DataKeeper is sharing the availablebandwidth with other applications, you may wish to limit the amount of bandwidth DataKeeper is allowed touse. DataKeeper includes a feature called Bandwidth Throttle that will do this. The feature is enabled via aregistry setting.Note: For additional information on both Compression and Bandwidth Throttle, see the topics below.• Registry Entries• Changing the Compression Level of an Existing MirrorDataKeeper for Windows Technical DocumentationPage 41
