Replication Sets
A replication set defines the data on a source machine that is to be protected by Storage Mirroring. Replication sets are
defined by the volumes, directories, files, or wild card combinations that are to be replicated to the target. Creating multiple
replication sets allows you to customize sets of data that need to be protected.
Replication Set Rules
Replication sets are created by defining rules. Each replication set rule consists of:
! Path—The path including volume, drive, directory, file, and/or wild card
! Include—If the path and/or file is to be included in the files sent to the target
! Exclude—If the path and/or file is not to be included in the files sent to the target
! Recursive—If the path should automatically be applied to the subdirectories of the named directory
For example, a replication set rule might be
volume\directory\* inc, rec
This specifies that all files contained in the volume\directory path are included in the replication set. Because recursion is set,
all files and subdirectories under volume\directory are also included. The replication set becomes a list of replication set rules.
For example, suppose you want to protect your network server which contains an important customer database. You might
create a replication set with the following rule.
\exchsrvr\*.db inc, rec
This rule includes all database files from the exchsrvr directory. Recursion is specified with this rule so all .db files in any
subdirectory under the exchsrvr directory will also be included in the replication set.
NOTE: Rules can be written for paths that do not currently exist. To enter a nonexistent path, you will have to
manually enter the rule.
NOTE: Replication set rules are limited in length meaning that the entire volume\directory\filename including slashes,
spaces, periods, extensions, cannot exceed 259 characters.
Storage Mirroring can mirror, replicate, verify, and restore file names up to 32,760 characters, although each
individual component (file or directory name) is limited to 259 characters. File names longer than 32,760
characters (due to the concatenation of the source and target paths) will be skipped and logged to the Storage
Mirroring log file and the Windows Event Viewer.
