TAPE OWNERS, PROTECT YOURSELF
 
     If you use the 20,000 series tape reels or the 400,000 series
tape cartridges, you're responsible for making your own backups and
for storing your backups at a remote location, if needed.
     The UKCC does not make automatic backups of the 20,000 series
tape reels or the 400,000 series tape cartridges, nor do we include
these in any offsite storage procedure.
 
WHY BACKUP?
     The consequences of not backing up your data depends upon the
importance of the data and the difficulty required to recreate the
data if the original tape becomes unavailable for any reason.  For
example, some critical data on tape may have no original source
documents or data printer listings from which to recreate the data.
The destruction of the tape could cause the data to be lost forever.
     You should back up the data at the end of every update process,
and keep a copy at an offsite location.
 
WE CAN HELP YOU
     Although backing up this type of data is the responsibility of
the owner, help is available from a UKCC Consultant in 111 McVey Hall,
or from the UKCC Security Officer, Jack Coffman, jack@pop.uky.edu.
     Of course, you must make the final decisions as to the frequency
of backups, the number of backups to maintain, and whether to keep a
backup at an offsite location.  These decisions should be based on the
type of data you're backing up, how important the data is to you, and
how difficult it would be to recreate that data in case of an
emergency.
     We will be glad to help you determine these factors; just ask.
 
DOING IT YOURSELF
     To create a backup copy of a tape, bring another tape to the UKCC
Data Center.  Then just copy the tape using the following sample JCL.
     To copy a standard label (SL) tape to another standard label (SL)
tape:
 
//FATCOPY  JOB  ,yourname,TIME=(,15)
//*LOGONID logonid
//*PASSWORD password/newpassword
//FATAR     EXEC PGM=FATAR
//SYSPRINT  DD SYSOUT=A
//TAPESUMM  DD SYSOUT=A
//SYSUDUMP  DD SYSOUT=A
//TAPEIN DD UNIT=3480,
//          LABEL=(,SL),
//          DSN=first.filename,
//          DISP=OLD,
//          VOL=SER=tapein
//TAPEOUT   DD UNIT=3480,
//          VOL=SER=tapeout,
//          DSN=first.filename,
//          LABEL=(,SL),
//          DISP=(NEW,KEEP)
//SYSIN     DD *   ANALYZE  KEEP,VERIFY
  /*
 
     To copy a non-standard label (NL) tape to a standard label (SL)
tape:
 
//FATCOPY  JOB,  yourname,TIME=(,15)
//*LOGONID logonid
//*PASSWORD password/newpassword
//FATAR     EXEC PGM=FATAR
//SYSPRINT  DD SYSOUT=A
//TAPESUMM  DD   SYSOUT=A
//SYSUDUMP  DD   SYSOUT=A
//TAPEIN DD   UNIT=3480,
//          LABEL=(1,NL),
//          DISP=OLD,
//          VOL=SER=tapein,
//          DCB=(RECFM=fb,
//          LRECL=lr,
//          BLKSIZE=bsize)
//TAPEOUT   DD   UNIT=3480,
//          VOL=SER=tapeout,
//          DSN=first.filename,
//          LABEL=(1,SL),
//          DISP=(NEW,KEEP)
//SYSIN     DD   *   ANALYZE NUMFILES=n

DO IT REGULARLY
     Over time, the ability to retrieve data stored on magnetic tape
decreases.  This is usually because of deterioration of the physical
media and sometimes due to a loss of strength of the magnetic signal.
So files which are archived should be periodically renewed.
     If you don't renew/rewrite the tape for long periods of time, you
might not be able to retrieve the data.  We recommend that all
archived tapes be copied to a new tape at least once every 18 to 24
months.
     For more information about or help with backing up your tapes,
contact a Consultant in 111 McVey Hall, 257-1300,
helpdesk@pop.uky.edu.  Or contact the UKCC Security Officer, Jack
Coffman, at 257-2900, 218 McVey Hall, jack@pop.uky.edu.
