Создать "утройство" (файл или утройство для данных)

disk init
   name = "cmm_db_data_2",
   physname = "/sybase_devices/cmm_db_data_2.dat",
   size = "5000M"

Добавить это устройство к базе.

Дамп и восстановление

Для дампа и восстановления ТАБЛИЦ используется утилита bcp .
Подробнее почитать тут http://manuals.sybase.com/onlinebooks/group-as/asg1250e/util/@Generic__BookTextView/10086;pt=8630/*

Для дампа базы целиком используется isql:

isql
1> dump database cmm_db
2> to "./cmm_db.dump"
3> go
Backup Server session id is:  70.  Use this value when executing the
'sp_volchanged' system stored procedure after fulfilling any volume change
request from the Backup Server.
Backup Server: 4.41.1.1: Creating new disk file /DBAPP1/sybase/./cmm_db.dump.
Backup Server: 6.28.1.1: Dumpfile name 'cmm_db111080E7CC ' section number 1
mounted on disk file '/DBAPP1/sybase/./cmm_db.dump'
Backup Server: 4.188.1.1: Database cmm_db: 105464 kilobytes (1%) DUMPED.
...
Backup Server: 4.188.1.1: Database cmm_db: 8601706 kilobytes (73%) DUMPED.
Backup Server: 3.43.1.1: Dump phase number 1 completed.
Backup Server: 3.43.1.1: Dump phase number 2 completed.
Backup Server: 3.43.1.1: Dump phase number 3 completed.
Backup Server: 4.188.1.1: Database cmm_db: 8663424 kilobytes (100%) DUMPED.
Backup Server: 3.42.1.1: DUMP is complete (database cmm_db).

При этом дамп будет сохранен на сервере БД а не на том хосте где запускался isql
