NetBackup 8.2 (or greater) multiplexed tape backups may not be readable by media servers at versions pre 8.2
Severity
Potential Data loss
Description
NetBackup 8.2 allows for more than one job per second to run simultaneously which leads to backup IDs from multiple clients that could have the same unix time otherwise known as ctime
If there are multiplexed tape storage unit image copies that could potentially be affected, consider extending the retention length of the original backup images (copy 1) or any other copies made by media servers running NetBackup 8.2 or greater until any potentially corrupt copies can be identified and recreated from the original copy.
Action Required
Do not use alternate read hosts to duplicate/restore/verify multiplexed tape storage unit images written by NetBackup 8.2 or greater on a NetBackup media server running less than version 8.2.
