Brian, Maybe you defined the tape larger than it is? Are you sure the tape can hold 80M of data? Are you using hardware compression? Jean-Louis On 01/08/2014 09:13 AM, Brian Cuttler wrote: I'm not sure I understand this tape usage... 18% plus 75% 100%, isn't it? Amanda 3.3.0 Solaris

Jean-Louis, googled it... I had my numbers wrong, it can supposedly hold 800 Gig, and with HW compression up to 2x that. I should not have to adjust the tape length and no reason (that I can see) for dumps to take more than one tape. Its odd that I'm not seeing an end of media error message...
