That's exactly what it will do, unless you explicitly tell Amanda that a tape is out of commission. So, just like your traditional robot, it will cycle. HOWEVER, note that Amanda will not write to a tape that has been recently written, whether it's 5 GB or 150 GB. It does /not/ append to tapes (barring some painful and unnecessary manual configuration, that is). So, you're better off using small vtapes. Because if it only writes 5 GB to 150 GB in a 2 TB NAS, that remaining 145 GB is unavailable to Amanda until that vtape comes up for overwriting. > > Thanks for the help, > -- > Chris. > > V:916.974.0424 > F:916.974.0428
