Retention Periods with end dates beyond 2038, excluding Infinity
For NetBackup versions before 9.0, there is a retention period limitation. Due to UNIX epoch time and the year 2038 problem, any expiration time that exceeds January 19, 2038 is automatically set to expire on January 19, 2038. The images with such expiration times will expire in January 19, 2038 regardless of what the original intent of the retention levels was.
This issue does not apply to retention levels for which the retention period is set to Infinity. NetBackup never expires media with a retention set to Infinity unless instructed to do so by the NetBackup administrator.
Starting with NetBackup version 9.0, retention periods that extend beyond the year 2038 are supported. This retention period support is applicable not only to images but tape media as well.
Some backup images that are created with earlier versions may have expiration dates of January 19, 2038 after upgrade. You can correct the date issue with any of the images during upgrade or the records with end dates of January 19, 2038.
