#[/]fbackup -v -f /dev/rmt/0m -i /etc/passwd
fbackup(1004): session begins on Fri Feb 28 13:46:11 2003

其中第三行告警是为什么阿？这样到底是不是已经完成了？

你的磁带是不是该换了？

不会巴，磁带是新的阿，第一次用。我继续使用了fbackup命令如下：#[/]fbackup -v -f /dev/rmt/0m -i /etc/group
fbackup(1004): session begins on Fri Feb 28 13:58:54 2003
fbackup(3203): volume 1 has been used -1 time(s)
fbackup(3024): writing volume 1 to the output file /dev/rmt/0m
    1: / 2
    2: /etc 12
    3: /etc/group 1
fbackup(1005): run time: 28 seconds
fbackup(3055): total file blocks read for backup: 15
fbackup(3056): total blocks written to output file /dev/rmt/0m: 39
[/]fbackup -v -f /dev/rmt/0m -i /etc/passwd
fbackup(1004): session begins on Fri Feb 28 14:03:18 2003
fbackup(3203): volume 1 has been used 0 time(s)
fbackup(3024): writing volume 1 to the output file /dev/rmt/0m
    1: / 2
    2: /etc 12
    3: /etc/passwd 2
fbackup(1005): run time: 15 seconds
fbackup(3055): total file blocks read for backup: 16
fbackup(3056): total blocks written to output file /dev/rmt/0m: 39

“fbackup(3203): volume 1 has been used -1 time(s)”
“fbackup(3203): volume 1 has been used 0 time(s)”
什么意思，望指点，谢谢！

应该已经完成了!只有有警告,我有时备份也有,当时当我用清洗带清洗或换磁带后就没有了,我至少一周要清洗一次,

你可以看一下列出目前磁带里的内容的索引index,再打开index文件看一下是否有你备份内容
#frecover  -I  某个目录/index

或倒出磁带里内容看看,在当前目录下:
#frecover -xvF -i /etc/group
