Boot volume configuration
The target boot volume cannot be a dynamic disk configuration. The boot
volume is the disk volume that contains the Windows operating system
and supporting files. By default, the operating system files are in the
\Windows folder, and the supporting files are in the \Windows\System32
folder. The boot volume might be the same volume as the system volume,
but that configuration is not required.
System path
The source and the target must have the same system path. The system
path includes the location of the Windows files, Program Files, and
Documents and Settings.
Storage Mirroring Recover path
Storage Mirroring Recover must be installed on the same volume on the
source and the target.
Storage Mirroring Recover data state
The source should be from a time when the Storage Mirroring Recover
data state is good. If you are using snapshots, you may want to use a
snapshot from the last good data state.
Capacity and free space
The target must have enough space to store the data from the source. This
amount of disk space will depend on the applications and data files you
are protecting. The more data you are protecting, the more disk space you
will need. You must also have enough space on the target to process and
apply the system state data.
Storage Mirroring Recover performs several validation checks to
determine if adequate disk space is available. First, the target must have
enough free space on its system volume to hold the entire volume(s) (free
and used) from the source. If this first validation check passes, then no
additional checks are necessary. Otherwise, there must be at least
enough free space on the target system volume to store the system path
(including the location of the Windows files, Program Files, and
Documents and Settings) from the source. If this second validation check
passes, then no additional checks are necessary. If this second validation
fails, Storage Mirroring Recover will check to see if a previous failover
may have been attempted. Since Storage Mirroring Recover can reuse the
disk space from a previous failover attempt, it will add the size of that data
to the amount of free space available. If that is enough space for the
