Sybase数据库技术，数据库恢复专家

以下操作均由sybase用户来做：

新建一个脚本文件，譬如/sybase/script/dump.sh
类容如下

$ cat dump.sh
/sybase/OCS-12_5/bin/isql -Usa -P******* -S******* -i /sybase/script/dump.sql -o /sybse/script/dump.log
mv /caiwubackup/backup/cwbase1.bak /caiwubackup/backup/cwbase1_`date +%Y%m%d`.bak
mv /caiwubackup/backup/cwbase2.bak /caiwubackup/backup/cwbase2_`date +%Y%m%d`.bak
mv /caiwubackup/backup/cwbase3.bak /caiwubackup/backup/cwbase3_`date +%Y%m%d`.bak
mv /caiwubackup/backup/cwmaster.bak /caiwubackup/backup/cwmaster_`date +%Y%m%d`.bak
mv /caiwubackup/backup/master.bak /caiwubackup/backup/master_`date +%Y%m%d`.bak

（注意：`号是在键盘左上角和波浪线在一起的那个键上，不是单引号）

在同一个目录下新建脚本dump.sql
类容如下

$ cat dump.sql

dump database cwbase1 to "/caiwubackup/backup/cwbase1.bak"
go
dump database cwbase2 to "/caiwubackup/backup/cwbase2.bak"
go
dump database cwbase3 to "/caiwubackup/backup/cwbase3.bak"
go
dump database cwmaster to "/caiwubackup/backup/cwmaster.bak"
go
dump database master to "/caiwubackup/backup/master.bak"
go

制定一个定时计划，每天晚上23点30开始备份数据库

$crontab -e
30  23 *  *  *  /sybase/script/dump.sh

根据你本机的实际情况，修改相关数据库名称和路径。
