connection, the chance of a conflict occurring because application resources
are attempting to open files exclusively while GeoCluster is mirroring those
files is removed.
● Orphan files—An orphan is a file that exists in the target location but is not in
the source location. You can enable the resource to remove or delete
orphans during a mirror. If you choose to move orphan files, specify the
location where you want to move them. You should not select the system
volume for the orphan files because it could impact the stability of the cluster
service.
5. Compression—If you want to configure Storage Mirroring Recover compression,
verify that Enable Compression is selected. Depending on the compression
algorithms available for your operating system, you may see a slider bar indicating
different compression levels. Set the level from minimum to maximum compression
to suit your needs.
6. Mirror Properties—This tab controls the Storage Mirroring Recover mirroring
process.
● Full Mirror—All files in the replication set will be sent from the source to the
target.
● File differences—Only those files that are different based size or date and
time will be sent from the source to the target.
● Send data only if Source is newer than Target—Only those files that
are newer on the source are sent to the target.
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.
● Use block checksum—For those files flagged as different, the mirror
performs a checksum comparison and only sends those blocks that are
different.
● Calculate Replication Set size prior to mirror—Determines the size of the
replication set prior to starting the mirror. The mirroring status will update the
percentage complete if the replication set size is calculated.
