Even if your drive is on the list below, please check the
98
<A HREF="Testing_Your_Tape_Drive.html#btape1">Tape Testing Chapter</A> of this manual for
99
procedures that you can use to verify if your tape drive will work with
100
Bacula. If your drive is in fixed block mode, it may appear to work with
101
Bacula until you attempt to do a restore and Bacula wants to position the
102
tape. You can be sure only by following the procedures suggested above and
106
It is very difficult to supply a list of supported tape drives, or drives that
107
are known to work with Bacula because of limited feedback (so if you use
108
Bacula on a different drive, please let us know). Based on user feedback, the
109
following drives are known to work with Bacula. A dash in a column means

Unsupported Tape Drives
284
Previously OnStream IDE-SCSI tape drives did not work with Bacula. As of
285
Bacula version 1.33 and the osst kernel driver version 0.9.14 or later, they
286
now work. Please see the testing chapter as you must set a fixed block size.
289
QIC tapes are known to have a number of particularities (fixed block size, and
290
one EOF rather than two to terminate the tape). As a consequence, you will
291
need to take a lot of care in configuring them to make them work correctly

304
Unless you have patched the pthreads library on FreeBSD 4.11 systems, you will
305
lose data when Bacula spans tapes. This is because the unpatched pthreads
306
library fails to return a warning status to Bacula that the end of the tape is
307
near. This problem is fixed in FreeBSD systems released after 4.11. Please see the
308

Tape Specifications</A>
334
If you want to know what tape drive to buy that will work with Bacula,
335
we really cannot tell you. However, we can say that if you are going
336
to buy a drive, you should try to avoid DDS drives. The technology is
337
rather old and DDS tape drives need frequent cleaning. DLT drives are
338
generally much better (newer technology) and do not need frequent
342
Below, you will find a table of DLT and LTO tape specifications that will
343
give you some idea of the capacity and speed of modern tapes. The
344
capacities that are listed are the native tape capacity without compression.
345
All modern drives have hardware compression, and manufacturers often list
346
compressed capacity using a compression ration of 2:1. The actual compression
347
ratio will depend mostly on the data you have to backup, but I find that
348
1.5:1 is a much more reasonable number (i.e. multiply the value shown in
349
the table by 1.5 to get a rough average of what you will probably see).
350
The transfer rates are rounded to the nearest GB/hr. All values are provided
351
by various manufacturers.
354
The Media Type is what is designated by the manufacturers and you are not
355
required to use (but you may) the same name in your Bacula conf resources.
