IT28106: INCREMENTAL BACKUP BACKS UP UNCHANGED FILES WITH DATES BEFORE JANUARY 1, 1970 OR WITH DATES AFTER FEBRUARY 7, 2106

APAR status

• Closed as program error.

Error description

• During backup or archive operations, the client incorrectly
  stores atime, mtime, ctime, timestamps on the IBM Spectrum
  Protect Server and if the timestamp is outside the following
  range 'January 1, 1970 through February 7, 2106'. This can cause
  the file to be backed up even if it has not changed.
  As a result, the restore and retrieve will restore an incorrect,
  arbitrary timestamp.
  When query backup command is issued with -detail option, it will
  also display incorrect info for the objects that were backed up
  with the incorrect date.
  IBM Spectrum Protect Versions Affected: All Client versions are
  affected including HSM for AIX JFS2 except Windows, AIX GPFS,
  Linux GPFS
  Customer/L2 Diagnostics:
  Enable trace using traceflag service.
  Initial Impact: Medium
  Additional Keywords:  mtime modified date backup file everytime
  

Local fix

• - The affected files can be touched to set them to the current
  date or any date in the valid date range.
  - Set each backup management class's copy group value VEREXISTS
  to NOLIMIT or, at the least, to something no less than the
  RETEXTRA value, assuming incremental backups run once a day.
