但是我其它的备份:

如le0backup：
run{
allocate channel t1 type 'sbt_tape' parms 'ENV=(tdpo_optfile=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
backup incremental level 0 tag 'db0' format 'db0_%t_%s_%p' diskratio=0 database skip readonly;
sql 'alter system archive log current';
backup format 'arch_%t_%s_%p' diskratio=0 archivelog all delete input;  
release channel t1;
}
就不报错！需且是正常备份！！！！！

这里没问题吗？

sshd

did you have proper tape driver? (sbt_tape)

这些错误应该都是跟tape 管理软件相关的。找他们可能更有用。
