1210 - Summary/Objective
1211 -
121101 - Follow up ref SDS 53 0000, ref SDS 52 0000.
121102 -
121103 - Used new 45M tapes received from Exabyte on 020606, ref SDS 49 0001,
121104 - for a full file backup on c13.  This required two tapes, because there
121105 - are about 8G now on the disk.
121106 -
121107 - Verify failed.  It crashed the system, causing a re-boot.
121108 -
121109 -  ..
121110 - As a result of persistant failures, on 021012 I changed the procedure
121111 - to use a pkzip op that only backups changed work files each day.
121112 - ref SDS 54 0001  This picks up about 50MB per day, and it is stored on
121113 - the e drive.  We can do this for several months, and back that up with
121114 - the full file procedure using the Mammoth LT tape drive once a month.
121115 -
121116 - On ths occassion I observed the end of the verify op, because it was
121117 - necessary to change the tape.
121118 -
121119 -  ..
121120 - When the second tape was loaded into the drive, I clicked the program
121121 - prompt to continue the backup.  Novaback software showed backup
121122 - continued, but after several minutes, there was a message saying the
121123 - tape was rewinding at a time when there was still about 1.5 GB to
121124 - complete the backup.  The backup seemed to continue for about 500MB or
121125 - so, and the computer suddently re-booted.
121126 -
121127 - Possibly the rewinding event during a period when the software also
121128 - showed that backup operations were underway is a scenario that is
121129 - familiar to Exabyte.
