Veritas NetBackup™ Snapshot Client Administrator's Guide

Sync region size in MB parameter (UNIX only)

Specifies the size in MB of each I/O request that is used when the regions of a volume are synchronized. Specifying a larger size causes synchronization to complete sooner, but with greater effect on the performance of other processes that access the volume. 1 MB (the default) is the minimum value that is suggested for high-performance array and controller hardware. The specified value is rounded to a multiple of the volume's region size.

This option is the same as the iosize=size parameter on the VxVM vxsnap command. For more details on the iosize=size parameter, see the Veritas Volume Manager Administrator's Guide.
