Imported Tape, the expiration date changed

iwantam
Level 3
Hi All, 
 
We need to import Tapes from our older system to the current system. Inside the tape is the 5 year retention backup we backup 2 years ago. The problem was when we imported the tape, the expiration date changed, became a 5 years from now instead of 3 years for now.
 
Is this a normal behavior? Can we make the expiration date just follow the original tape?
 
Regards, 
 
Iwan

The images are imported with original retention level. 
The period that matches the level is then applied to the images.

https://www.veritas.com/support/en_US/article.TECH43584     
Once the Phase 2 import is complete, the image has the same retention level as the original backup and a new expiration date calculated as the import date plus the retention period defined currently in Host Properties for the original backup's retention level.  

Both 3 year and 5 year retentions are custom levels. The defaults are as per this doc:   https://www.veritas.com/content/support/en_US/doc/123533878-127136857-0/v123544048-127136857

This means that retention level was probably changed in Host Properties in the meantime.

Thank you for answering my question Marianne now I know something more about the import.

But I see the custome retention has the same definition on our old NetBackup server and the new one.

The old one:

# bpretlevel -s

Retention  Retention  Equivalent
  Level     Period       Days
--------- ----------- ----------
    0     1 week         7
    1     3 weeks        21
    2     1 day          1
    3     1 month        31
    4     5 weeks        35
    5     3 months       93
    6     2 weeks        14
    7     7 years        2555
    8     1 year         365
    9     infinity
   10     expires immediately
   11     5 years        1825
   12     infinity
   13     infinity
   14     infinity
   15     infinity

The new one:

You will notice that there is no retention level with 3 year expiration. 

The only logical explanation is that level 11 was set to 3 years when the backup was made 2 years ago. 
In the meantime, level 11 was changed to 5 years.

The old backup was imported with level 11. 
That is why the imported backup now has 5 year retention/expiration.
