l Initial Verification Start—Specify when you want a verification process to be
performed. You can select the immediate date and time by clicking Now, or
enter a specific Date and Time. The down arrow next to Date displays a
calendar allowing easy selection of any date. Time is formatted for any AM or
PM time.
l Reverification Interval—Select this option to repeat the verification process
at the specified interval. Specify an amount of time and choose minutes,
hours, or days.
l Remirror files to the target automatically—When this option is enabled,
Storage Mirroring Recover will verify the data, generate a verification log, and
remirror to the target any files that are different on the source. If disabled,
Storage Mirroring Recover will verify the data and generate a verification log,
but no files will be remirrored to the target.
l Only if source file is newer than target copy—If you are remirroring
files with the verification, you can specify that only files that are newer
on the source than on the target are remirrored.
Note: If you are using a database application, do not use the newer
option unless you know for certain you need it. With database
applications, it is critical that all files, not just some of them that
might be newer, get mirrored.
l Use block checksum comparison/delta block transfer—When this option
is enabled, Storage Mirroring Recover only those blocks that are different will
be identified in the log and/or remirrored to the target. If disabled, entire files
will be identified and/or remirrored.
Note: Database applications may update files without changing the date,
time, or file size. Therefore, if you are using database applications,
you should use the block checksum comparison to ensure proper
verification and remirroring.
