2011-04-01 15:16:43 8241  8239 /home/informix/bin/onbar_d complete, returning 0 (0x00)

[root@smtp ~]# grep 199436 /home/informix/bar_act.log

0级备份是2：00做的，做完物理恢复后，做逻辑日志恢复时，却要求0级备份之前的逻辑日志文件（ 2011-04-01 01:06:29 26691  26689 Completed backup logical log 199436 (Storage Manager copy ID: 294070944 0).），这正常吗？

注：是将0级备份同步到另外一台新机器上进行的恢复
