CalculateBy
Volume
Calculates the approximate size of a replication set by using the size of the
volume and subtracting the free space
Values:
0 Disabled
1 Enabled
Default:
0
GUI Setting: None
If your replication set contains a large number of files, for example, ten
thousand or more, you may want to disable the calculation of the replication
set size so that data will start being mirrored sooner. If calculation is enabled,
the source calculates the file size before it starts mirroring. This can take a
significant amount of time depending on the number of files and system
performance.
Disabling calculation will result in the mirror status not showing the
percentage complete or the number of bytes remaining to be mirrored.
CalculateByVolume can be enabled as a workaround. This setting will get
the amount of disk space in use for the entire volume from the operating
system, so the calculation occurs instantaneously. However, if the entire
volume is not being replicated, the mirror percentage complete and bytes
remaining will be incorrect accordingly.

ChecksumAll Setting to allow for the difference checksum option on mirror, verify, or
restore to ignore the date, time, and size of the file and perform a checksum
calculation on all files
