When you specify a dump device:
You can specify the dump device as a literal, a local variable, or a parameter to a stored procedure.
You cannot dump to or load from the “null device” (on UNIX, /dev/null; not applicable to PC platforms ).
When dumping to or loading from a local device, you can use any of the following forms to specify the dump device:
An absolute path name
A relative path name
A logical device name from the sysdevices system table
The Backup Server resolves relative path names using Adaptive Server’s current working directory.
When dumping or loading over the network:
You must specify the absolute path name of the dump device. You cannot use a relative path name or a logical device name from the sysdevices system table.
The path name must be valid on the machine on which the Backup Server is running.
If the name includes any characters except letters, numbers, or the underscore (_), you must enclose it in quotes.
If you dump a transaction log using with standby_access, you must load the dump using with standby_access.
The following examples use a single tape device for dumps and loads. (It is not necessary to use the same device for dumps and loads.)
On UNIX:
dump database pubs2 to "/dev/nrmt4" load database pubs2 from "/dev/nrmt4"
On Windows NT:
dump database pubs2 to "\\.\tape0" load database pubs2 from "\\.\tape0"
You can also dump to an operating system file. The following example is for Windows NT:
dump database pubs2 to "d:\backups\backup1.dat" load database pubs2 from "d:\backupbackup1.dat"
