061001 - Background.
061003 -  ..
061004 - On 041116 received c14 from Dell. ref SDS 2 0001  Procurement was
061005 - developed on 041101. ref SDS 1 XK4L  The system was configured on
061006 - 041118. ref SDS 3 0001
061008 -  ..
061009 - On 050128 Dell replaced the computer. ref SDS 5 0001
061011 -  ..
061012 - We have been using c11 with an internal tape drive for backup the past
061013 - 10 years or so.  This has become increasingly awkward and slow by
061014 - selecting and transferring files from c14 and c15 for monthly backups.
061015 - The tape drive has failed verify operations consistently for several
061016 - years, e.g., on 061014, ref SDS 7 PS3K, earlier on 060209. ref SDS 6
061017 - PS3K  Data transfer rate for backing up has slowed to half the normal
061018 - time because tapes are overwritten.  This can be solved to increase
061019 - DTR by formatting tapes, but this takes several hours for each tape,
061020 - e.g. reported on 070116. ref SDS 8 0001  Additionally, restoring files
061021 - backed up on tape is very slow.
061023 -  ..
061024 - The past few years there have been reports that people are using large
061025 - size hard drives to store files with conventional file management
061026 - tools.
061028 -  ..
061029 - Decided today to explore buying a hard drive for backup, as explained
061030 - below. ref SDS 0 J19W
061031 -
061032 -          [On 070309 ordered 500 GB external hard drive from Dell for
061033 -          backup. ref SDS 9 IE5L
061034 -
061035 -          [On 070312 received Hitachi 500 GB hard drive, and backed up
061036 -          c14. ref SDS 10 IE5L
061038 -           ..
061039 -          [On 070314 developed new full file backup system using new
061040 -          500 GB hard drive. ref SDS 11 427J

061054 -         ..
061055 -    3.  Just checking.  In 2005, you provided excellent support
061056 -        resolving configuration issues on a Dell computer we purchased,
061057 -        e.g., see the record on 050120. ref SDS 4 3W8F
061059 -         ..
061060 -    4.  I want to upgrade the system with a large hard drive 300 - 500
061061 -        GB for backups, to replace an exabyte tape drive.  Where can I
061062 -        get a list of hard drive upgrades for the computer received
061063 -        from Dell on 050128. ref SDS 5 LQ7J
