There's an extensive discussion of the interaction of hard-links & Netbackup in on pages 114-116 of the v5.x SAG (vol 1).
Hard-links, as you're probably aware, can't cross filesystem boundaries so restoring to a mixed set of filesystems is bound to cause link issues. In a DR situation, I suspect your filesystems will be similar to your primary setup and these problems might not manifest. -M -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Christopher Jay Manders Sent: Monday, December 12, 2005 1:15 PM To: [email protected] Subject: [Veritas-bu] Hard symbolic link restore issue... We have a restore problem that Legato (the old backup solution) did not seem to have with our iPlanet IMAP mail store .... BACKGROUND: We have a huge IMAP datastore that resides on a SAN. There are multiple front-ends for folks to get their mail from, named 'imap1, imap2,...'. When someone wants their mail spool files restored, those go onto a separate system that does not have all of the same data with the same inodes. So all Hard Links are not restoring properly Here is a snippet of the error a standard restore gives: 09:41:59 (447272.005) /imap1-mailstore101/=user/c2/10/=+X+Xaa/98/69851.msg 09:41:59 (447272.005) Changed /imap1-mailstore101/=user/c2/10/=+X+Xaa/98/69851.msg to /store/restore/restore-XXaa//98/69851.msg 09:41:59 (447272.005) Could not link /store/restore/restore-XXaa/98/69851.msg -> /imap1-mailstore101/=user/85/c2/=+Y+Ybb/09/937.msg. Errno = 18: Cross-device link QUESTION: Is there a way to back up and restore the data in the links for these one-off requests for a user's mail store restore that we get daily, while also keeping the knowledge of the link..so in a REAL disaster we can restore to a system with the proper inode structures with the symbolic links intact?
