I installed a trial DP8 and verified, that the restriction is still valid. At the time of backup a warning is shown:
[Warning] From: BSM@cellserver.mydom.int "test" Time: 26.2.2014 9:48:41 [61:20005] Hard link detection is not supported with enhanced backups. Hard links for object 'cellserver.mydom.int:/' will be backed up as files.
After restore, test hard links are really transformed to separated files:
Original: # ll -i /bin/*ed 789835 -rwxr-xr-x. 2 root root 53400 Mar 1 2010 /bin/ed 789835 -rwxr-xr-x. 2 root root 53400 Mar 1 2010 /bin/red Restored: # ll -i /root/testHL/bin/*ed 1444075 -rwxr-xr-x. 1 root root 53400 Mar 1 2010 /root/testHL/bin/ed 1444124 -rwxr-xr-x. 1 root root 53400 Mar 1 2010 /root/testHL/bin/red
Unfortunately, it seems as HP doesn't make efforts to eliminate the hard link restriction of an enhanced incremental backup. That's a pity, because it excludes some significant tasks - e.g. backup of operating system. It significantly decreases usability of this technology.
