In the dump command, you can specify the maximum size of the tape file in terms of tape blocks. For example, if you want the maximum tape file to be 2 GB, specify 2,097,151. This specifies that the largest tape file can contain 2,097,151 tape blocks, which are 1 kilobyte each. The tape file size must be equal to or greater than the blocking factor; otherwise, the dump process terminates.
If you do a remote backup or plan to restore the backup on a system other than the filer, you might need to specify a tape file size. Some systems support tape files of a limited size; for example, some Solaris systems do not support tape files larger than 2 GB.
To specify a tape file size, complete the following steps.
| 1 | |
| 2 | Include the tape file size, in kilobytes, in the dump command as an argument to the B option. The size applies to all tape files in the backup. |
The following command backs up the /vol/vol0 volume using a tape file size of 2,097,151, so that a tape file is no larger than 2 GB:
