显示磁带机上的文件列表： tar tvf /dev/rmt/ctape1www.come on babyiTbulo.como2AuE
从磁带机上拷贝文件： tar xvf /dev/rmt/ctape1www.come on babyiTbulo.como2AuE
注意磁带机的容量大小和磁带的容量大小一定要匹配。www.come on babyiTbulo.como2AuE
3， 将磁带机设备加入到SYBASE的备份设备中：www.come on babyiTbulo.como2AuE
sp_adddumpdevice dev_name "/dev/rmt/ctape1"www.come on babyiTbulo.como2AuE
www.come on babyiTbulo.como2AuE
二。磁带机的备份www.come on babyiTbulo.como2AuE
SCOUNIX上SYBASE的磁带机常用备份命令：
[语法]
dump database database_name
to stripe_device [at backup_server_name]
[density = density_value,
blocksize = number_bytes,
capacity = number_kilobytes,
dumpvolume = volume_name,
file = file_name]
[stripe on stripe_device [at backup_server_name]
[density = density_value,
blocksize = number_bytes,
capacity = number_kilobytes,
dumpvolume = volume_name,
file = file_name]]
[[stripe on stripe_device [at backup_server_name]
[density = density_value,
blocksize = number_bytes,
capacity = number_kilobytes,
dumpvolume = volume_name,
file = file_name]]...]
[with {
density = density_value,
blocksize = number_bytes,
capacity = number_kilobytes,
dumpvolume = volume_name,
file = file_name,
[dismount | nodismount],
[nounload | unload],
retaindays = number_days,
[noinit | init],
notify = {client | operator_console}
} ]
1，向磁带设备转储MBFEWKDB库：
dump database MBFEWKDB to "/dev/ctype1"
2,14天内不能覆盖磁带：
dump database MBFEWKDB to "/dev/ctype1" with retaindays=14
3,覆盖磁带上原有数据：
dump database MBFEWKDB to "/dev/ctype1" with initwww.come on babyiTbulo.como2AuE
www.come on babyiTbulo.como2AuE
