If you select files with alternate data streams, keep in mind the following.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.This also includes denying permission to the Everyone group because this group contains the system account. If any directory or file contained in your job specifically denies permission to the system account or the account running the Double-Take service, the attributes of the file on the target will not be updated because of the lack of access.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.For example, if your 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. If you are mirroring/replicating from an NTFS source to a FAT target, you may see additional error messages in your Double-Take Availability log file because the target file system cannot handle the NTFS attributes or file permissions.To work around this issue, make sure both volumes are NTFS. 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.If you have mixed file systems, keep in the mind the following.If you are protecting your system state and data using full-server protection, Double-Take Availability will automatically gather and replicate all necessary system state data, including files for the operating system and applications. The only exception to these exclusions is for the full-server workloads.
DOUBLETAKE SOFTWARE DRIVER
Additionally, Double-Take Availability does not mirror or 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 Double-Take Availability disk-based queue logs.

Some reparse points are mirrored and replicated, including CommVault Data Migrator and BridgeHead Software HT FileStore.ĭouble-Take Availability does not mirror or replicate items that are not stored on the file system, such as physical volume data and registry based data. Files can be mirrored and replicated across mount points, even though mount points are not created on the target.
Mirrored and 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.
