使用ontape 备份数据到磁盘上，怎么设置？

wysfenghuo007

我是如下设置的：
# System Archive Tape Device

TAPEDEV         /backup/databackup/Tapebackup/tapedev       # Tape device path
TAPEBLK         32              # Tape block size (Kbytes)
TAPESIZE        10240           # Maximum amount of data to put on tape (Kbytes)

# Log Archive Tape Device

LTAPEDEV        /backup/databackup/Tapebackup/ltapedev       # Log tape device path
LTAPEBLK        32              # Log tape block size (Kbytes)
LTAPESIZE       10240           # Max amount of data to put on log tape (Kbytes)

其中tapedev和ltapedev是以informix用户创建的，权限：660，但是我运行ontape -s -U geo3d出现如下错误：
Please enter the level of archive to be performed (0, 1, or 2) 0

Please mount tape 1 on /backup/databackup/Tapebackup/tapedev and press Return to continue ...
could not write archive tape

把TAPEBLK,TAPESIZE,LTAPEBLK,LTAPESIZE屏蔽掉，也出错。把数据备份到磁盘具体怎么设置？

full backup "TAPESIZE        10240   "只有 10MB, 你的數據庫有這麼小哦?
試一下 "TAPESIZE        4000000   "  4GB, 不夠再放大.

还有，每次备份前要创建出
/backup/databackup/Tapebackup/tapedev
和
/backup/databackup/Tapebackup/ltapedev
这两个文件。

首先感谢楼上高手的回答。我改了以下大小，还是出错。另外，tapedev和ltapedev我都已经创建好了，是不是每次都要删除，然后重新创建。
我修改参数如下；
TAPEDEV         /backup/databackup/Tapebackup/tapedev       # Tape device path
TAPEBLK         32              # Tape block size (Kbytes)
TAPESIZE        10240000           # Maximum amount of data to put on tape (Kbytes)

# Log Archive Tape Device

LTAPEDEV        /backup/databackup/Tapebackup/ltapedev       # Log tape device path
LTAPEBLK        32              # Log tape block size (Kbytes)
LTAPESIZE       10240000           # Max amount of data to put on log tape (Kbytes)

运行显示如下错误：
[informix@wangysh etc]$ ontape -s -U geo3d
Please enter the level of archive to be performed (0, 1, or 2) 0

Please mount tape 1 on /backup/databackup/Tapebackup/tapedev and press Return to continue ...
could not write archive tape.
Please mount tape 1 on /backup/databackup/Tapebackup/tapedev and press Return to continue ...

怎么解决？
能不能留下个qq或者msn的，好向您请教，我是新手刚开始学informix

Sorry, 上次說錯了,  TAPESIZE 不夠大會出現 Tape is full 和  mount tape 2
[informix@gt2 dbbk]$ ontape -s -U gt2
Please enter the level of archive to be performed (0, 1, or 2) 0
Please mount tape 1 on /work2/dbbk/gt2.bup.001 and press Return to continue ...
Tape is full ...
Please label this tape as number 1 in the arc tape sequence.
This tape contains the following logical logs:
6518
Please mount tape 2 on /work2/dbbk/gt2.bup.001 and press Return to continue ... ?
=======================================================
再試二下.
1. su - informix ; cd /backup/databackup/Tapebackup/ ; touch abc.test
以 informix 身份登入, 切換到 Tapebackup 目錄; 隨便產生一個檔案看是否能產生, 若是不行, 可能是上層或是上上層目錄權限有問題
2. TAPEDEV /tmp/tapedev
touch /tmp/tapedev ; chown informix.informix /tmp/tapedev ; chmod 660 /tmp/tapedev
ontape -s -L 0
=======================================================
full db backup 好像是用 ontape -s -L 0 就好;
ontape -s -U geo3d ; 好像是說要把 geo3d 從 None log 改成 Log ; 這個好像只要剛建立新數據庫時才要做; 以後都不用做才是

我按照你说的，操作了以下，还是不行
下面是我的操作步骤：
[informix@wangysh TapeBackup]$ touch xx
[informix@wangysh TapeBackup]$ rm -rf *
[informix@wangysh TapeBackup]$ cd ..
[informix@wangysh databackup]$ cd /
[informix@wangysh /]$ touch /backup/databackup/TapeBackup/tapedev
[informix@wangysh /]$ touch /backup/databackup/TapeBackup/ltapedev
[informix@wangysh /]$ chown informix:informix /backup/databackup/TapeBackup/tapedev
[informix@wangysh /]$ chowm informix:informix /backup/databackup/TapeBackup/ltapedev
-bash: chowm: command not found
[informix@wangysh /]$ chown informix:informix /backup/databackup/TapeBackup/ltapedev
[informix@wangysh /]$ chmod 660 /backup/databackup/TapeBackup/tapedev
[informix@wangysh /]$ chmod 660 /backup/databackup/TapeBackup/ltapedev
[informix@wangysh /]$ ontape -s -L 0

Please mount tape 1 on /backup/databackup/Tapebackup/tapedev and press Return to continue ...
could not write archive tape.
Please mount tape 1 on /backup/databackup/Tapebackup/tapedev and press Return to continue ...
