Hello, Are there new suggestions of backup strategies for many very large mailboxes (many GB and growing), with up to decades long retention period for deleted messages also? I searched the list archives and found the 2009 and 2010 threads interesting, but then proposed solutions may not scale to today and future needs. Guess that some form of tape archiving may be needed for such long periods. Our initial idea was to use some form of tiered storage, and decades of expunge delay. But messages flagged as deleted could sum up to millions on each of such large mailboxes years ahead, maybe causing dificulties with large directories (stat from tape backup sw, squatter). Will hashing mailboxes directories option help? Is there a clean way to move messages marked as deleted to another partition? http://en.wikipedia.org/wiki/Linear_Tape_File_System Maybe, if cyrus becomes compatible with NFS, then HSM solutions like http://www.openarchive.net could help. Do you have suggestions for this scenario? http://lists.andrew.cmu.edu/pipermail/info-cyrus/2002-November/017188.html http://lists.andrew.cmu.edu/pipermail/info-cyrus/2003-June/012997.html http://lists.andrew.cmu.edu/pipermail/info-cyrus/2005-September/019624.html http://lists.andrew.cmu.edu/pipermail/info-cyrus/2005-November/020218.html http://lists.andrew.cmu.edu/pipermail/info-cyrus/2009-January/030348.html http://lists.andrew.cmu.edu/pipermail/info-cyrus/2009-January/030356.html http://lists.andrew.cmu.edu/pipermail/info-cyrus/2010-February/032524.html http://lists.andrew.cmu.edu/pipermail/info-cyrus/2010-February/032533.html http://lists.andrew.cmu.edu/pipermail/info-cyrus/2011-February/034500.html Regards.
