Hi Guys, I have an IBM LTO 4 tape library with 4 tape drives . As we know capacity of LTO 4 tape is 800 GB.
Today I started a backup with already volume size of 750 GB after some time bacula marked volume as FULL and started writing to next volume. But after completion of job I seen that it is showing 850 GB data in tape one and around 70 GB data in tape two. I have tested a restore from these volumes. Which is working fine. output of list media command is below: Pool: BACKUP +---------+------------+-----------+---------+-----------------+----------+--------------+---------+------+-----------+-----------+---------------------+ | MediaId | VolumeName | VolStatus | Enabled | VolBytes | VolFiles | VolRetention | Recycle | Slot | InChanger | MediaType | LastWritten | +---------+------------+-----------+---------+-----------------+----------+--------------+---------+------+-----------+-----------+---------------------+ | 20 | A00040L4 | Full | 1 | 895,721,637,888 | 115 | 10,800 | 1 | 1 | 1 | LTO-4 | 2013-09-27 15:40:11 | | 21 | A00041L4 | Append | 1 | 74,331,177,984 | 10 | 10,800 | 1 | 2 | 1 | LTO-4 | 2013-09-27 15:52:35 | | 22 | A00042L4 | Append | 1 | 64,512 | 0 | 10,800 | 1 | 3 | 1 | LTO-4 | 0000-00-00 00:00:00 | | 23 | A00043L4 | Append | 1 | 64,512 | 0 | 10,800 | 1 | 4 | 1 | LTO-4 | 0000-00-00 00:00:00 | +---------+------------+-----------+---------+-----------------+----------+--------------+---------+------+-----------+-----------+---------------------+ Please tell me why this is happening. although it happens first time with me. :-) how it is possible to write 850 GB of data on a tape with 800 GB capacity?
