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?
TIA!
