● Calculating replication set size
● Deleting a replication set
Keep in mind the following notes when creating and working with replication sets and
connections.
● Limitations
● 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 Recover can mirror, replicate, verify, and restore paths up
to 32760 characters, although each individual component (file or directory
name) is limited to 259 characters. Paths longer than 32760 characters will
be skipped and logged.
● Do not name replication sets or select a target location using illegal
characters. Illegal characters include the following.
● period .
● question mark ?
● forward or backward angle bracket < >
● colon :
● quotation mark "
● forward or backward slash \ /
● asterisk *
● pipe or vertical bar |
● Error checking and avoidance
● Do not connect more than one replication set to the same location on a
target. You could overwrite or corrupt your data.
● Replication sets contain error checking to avoid inadvertent overwrites of the
replication set rules. When replication sets are modified, a generation
number is associated with the modifications. The generation number is
incremented anytime the modifications are saved, but the save is not allowed
if there is a mismatch between the generation number on the source and the
Replication Console. You will be notified that the replication set could not be
saved. This error checking safeguards the replication set data in the event
that more than one client machine is accessing the source’s replication sets.
● Storage Mirroring Recover will not replicate the same data from two different
replication sets on your source. The data will only be replicated from one of
the replication sets. If you need to replicate the same data more than once,
connect the same replication set to multiple targets.
