Thank you for a reply.
My target systems are AIX, Linux and Windows, so OpenVMS is not relevant.
In document "HP Data Protector software object consolidation" published in DP6 documentation set they say:
With the Enhanced incremental backup option enabled, hardlinks are not supported anymore.
This means that all hardlinks are backed up as normal files.
How HP Data Protector software handles hardlinks in general is defined through two options:
• Backup POSIX hard links as files (default not selected)
• Detect NTFS hardlinks (default not selected)
This means that, by default, HP Data Protector software backs up hardlinks on NTFS as normal files
and POSIX hard links as links.
Using enhanced incremental backup can now cause a conflict in case hardlinks should be backed up
as links. In such a case the following warning is listed inside the session output:
"[Warning] From: BSM@system1 Time: 8.5.2006 15:01:12
[61:20005] Hardlink detection is not compatible with enhanced backups.
Hardlinks for object 'bbn.deu.hp:/' will be backed up as files."
To suppress this warning in the future, modify the backup specification so that it will not contain
hardlink detection options.
• For Windows Filesystem objects, uncheck the "Detect NTFS hardlinks" option.
• For other Filesystem objects, check the "Backup POSIX hard links as files" option.
I have verified that in DP7 this is still valid, but I don't have built DP8 cell yet, so I can't to verify that for DP8.
As I don't know context of your HELP text citation, it is not clear, if the information is relevant to "enhanced incremental backup", too. Can you confirm that?
Did you ever try to backup hardlinks with enh. inc. backup?
