Hi All,
I duplicated tape using bpduplicate form LTO1 tape to LTO4 tape, the LTO1 is unencypted read using LTO2 tape drive and LTO4 is encrypted (using KMS). When I check the result of duplication, some of the images have the same size but some is not.

notes: duplicate copy no 3 is the LTO4 , we copy from the original (no 1 - LTO1)
As you can see the ads-bk_1135559670 & ds-bk_1132935093 have the consistence size but the fr-bck_119669942 has a differnet size for the copy no3. I have tested to restore the copy no3 (after promoting it to be the original), the restoration looked fine.
Is it a normal ? How can O check the duplication is OK?
Thank you
Iwan
