高手请指点！informix不备份Log是不是不能进行数据库dbspace的备份？使用ONBAR

NewLeaDeR

有个问题，informix不备份Log是不是不能进行数据库dbspace的备份啊？现在Log是循环利用的
我单独备份dbs时报这个错：

这里是将onconfig文件中的LTAPEDEV设为/dev/null时：
2006-03-15 09:45:42 25648  25646 /opt/informix/bin/onbar_d -b -L 0 ompdbs
2006-03-15 09:45:42 25648  25646 ERROR: Logical Logs will not be backed up / salvaged because
LTAPEDEV value is /dev/null . Normal backup (onbar -b) cannot be done
without logical logs being backed up, because restore of such backups
requires a logical log restore.

这里是将onconfig文件中的LTAPEDEV设为/opt/informix/nbu_log/logs时：（没有重启数据库）
