Replication capabilities
Storage Mirroring Replicate replicates file and directory data stored on any Windows file
system (FAT, FAT32, NTFS4, and NTFS5). Replicated items also include Macintosh
files, compressed files, NTFS attributes and ACLs (access control list), dynamic
volumes, files with alternate data streams, sparse files, and encrypted files. Files can be
replicated across mount points, even though mount points are not created on the
repository server. Some reparse points are replicated, including CommVault Data
Migrator and BridgeHead Software HT FileStore.
Typically, Storage Mirroring Replicate does not replicate items that are not stored on the
file system, such as physical volume data and registry based data. Nor does it replicate
NTFS extended attributes, registry hive files, Windows or any system or driver pagefile,
system metadata files ($LogFile, $Mft, $BitMap, $Extend\\$UsnJrnl, $Extend\\$Quota,
$Extend\\$ObjId, and $Extend\\$Reparse), hard links, or the Storage Mirroring Replicate
disk-based queue logs. However, if you are protecting a full-server, Storage Mirroring
Replicate will automatically gather and replicate all necessary system state data,
including files for the operating system and applications.
Note the following replication caveats.
1. If you have mixed file systems, keep in the mind the following.
a. If, on your source, you have a FAT volume mounted on a directory which
resides on an NTFS volume, these files will not be mirrored, regardless of the
target file system. Replication will work correctly. To work around this issue,
make sure both volumes are NTFS.
b. If you are mirroring/replicating from an NTFS source to a FAT target, you may
see additional error messages in your Storage Mirroring Replicate log file
because the target file system cannot handle the NTFS attributes or file
permissions. For example, if your protection job contains files with alternate
data streams, you will see messages indicating that there are unfinished
operations because the FAT file system cannot store the alternate data
stream information.
c. If you select a compressed file or folder from an NTFS partition and replicate
it to a FAT target, the attributes are lost, but the data is maintained.
2. If any directory or file contained in your protection job that specifically denies
permission to the system account or the account running the Storage Mirroring
service, the attributes of the file on the target will not be updated because of the
lack of access. This also includes denying permission to the Everyone group
because this group contains the system account.
3. If you select a dynamic volume and you increase the size of the volume, the target
must be able to compensate for an increase in the size of the dynamic volume.
4. If you select files with alternate data streams, keep in mind the following.
