Repairing storage directory ACLS on NTFS

ACLs for VOB and view storage directories are established when VOBs and views are created. These ACLs have a particular form that HCL VersionVault relies on.

Use NTFS-formatted disks to hold VOB and view storage directories on Windows® computers. NTFS file system objects are protected by security descriptors, which contain ownership information and access control lists (ACLs). FAT file systems do not support ACLs, so objects in FAT file systems can be protected only by the readonly attribute. This attribute is available in both NTFS and FAT, but it is not enforced and can be removed easily.

On NTFS, a VOB or view storage directory's ownership (its owner and primary group ID) is determined from the security descriptor on the directory root. On FAT file systems, this information is stored in the file identity.sd in the storage directory root. (For compatibility, the file identity.sd is also created on NTFS file systems). On both FAT and NTFS, the file groups.sd holds the supplementary VOB group list.

VOB and view storage directory ACLs

The following example shows the correct ACL for a VOB storage directory, sources.vbs, created by user NT_WEST\vvault_adm, whose primary group is user. The VersionVault administrators group is named versionvault.
