This permits btape to find the configuration parameters for your archive device generally a tape drive. The solution to the problem is: Aside from initial testing of tape drive compatibility with Baculabtape will be mostly used by developers writing new tape drivers.

It then writes at least one more Bacula block to a second tape. In order for Bacula to run in fixed block mode, you must include the following records in the Storage daemon's Device resource definition:. Bacula's preferred method ulttium working with tape drives sequential devices is to run in variable block mode, and this is what is set by default.
Try to set any fixed block size to something like 64, bytes or larger if your drive will support it. Even in variable block mode, with the exception of the first record on the second or subsequent volume of a multi-volume backup, Bacula will write blocks of a fixed size. When the file is re-written, answer the question, and Bacula will run without using block positioning, and it should recover your files.

Thank u in advance. You only need to mount a blank tape, enter the command, and the output should be reasonably self explanatory. However, functions like Polling the drive do not work correctly if there is no tape in the drive. Hhp is also a driver for the tape library but most applications don't require the library driver to be installed so you might not need it.
Note, I have chopped off the beginning of the line with the date and machine name for presentation purposes. This can be an extremely time consuming process here it is about 6 hours to fill a full tape. The server team can only test and officialy support a manageable set of configurations and that combination didn't make the cut. If you have reached this point, you stand a good chance of having everything work. If you do not successfully complete the above test, please resolve the problem s before attempting to use Bacula.
According to the documentation, one may never write an amount of data that is not the exact multiple of the blocksize it is not specified if an error occurs or if the the last record is padded. I have tried installing the drivers in various different ways all with the same result. This is a User Mode device.

For the program to work, it must find the identical name in the Device resource of the configuration file.
Note, that btape writes random data to the tape when it is filling it. If Bacula is configured to write fixed block sizes, it will pad the last block of the Job to ulteium correct size.
Most systems, but unfortunately not all, set the density to the maximum by default.
