Hello Ankush,

This is occuring with just a few tapes. Most of them seems to me they are fine. The number of bytes written to tape is variable since it will depend on specific characteristics of your backup data (number of files, file sizes, compression, etc.).

In the cases that a few number of bytes is written (MediaId 124 and 125, for example), it is possible that you have problems with your media. Is it possible for you to run some tests with btape and these specific medias?

If this is a recent situation/problem, than it would be fine to check the cleanning tape/process too.

Best regards,

Ana

Hello Ankush,

Bacula marks a volume as Full when Maximum Volume Bytes (if specified in Pool resource) or if it reaches de end of the medium you are using (a disk partition, a tape, etc.).

Based only on your list media output, in some cases we can say that the end of medium was reached, but this is not true for some volumes.

Could you post more information that could be useful to help you? Could you post your Bacula log lines containing "End of medium on Volume"? An output of the command "lsscsi -g" would be helpful as well.

Best regards,

Ana

Hi Team,

Bacula version 7.0.5

Using tape LTO-4 with autochanger, I notice some tapes are not fully utilized, still show “VolStatus” as Full.

Some tape are utilized full or beyond the capacity.

Please suggest me how to avoid under utilization of tapes.

Thank you,
