archive_copy_dir
This parameter defines the directory used by BRARCHIVE to back up the offline redo log files to a local disk.
Syntax:
archive_copy_dir = <dir>Default: First value of the parameter
backup_root_dirRequired value: A directory in which the offline redo log files should be archived.
This is generally only required when you are working with a two-phase archiving procedure, which is similar to a
Two-Phase Backup. The offline redo log files are first collected in a directory on a disk and then written to tape using BRARCHIVE option -a or external means. If external tools are used, the user is responsible for archiving to tape and for restoring from the tape to the disk, if this become necessary in connection with a recovery.
BRARCHIVE archiving to disk should only be used in the situations mentioned above. In all other cases the offline redo log files must always be archived to tape. Archiving to disk is not a substitute for archiving the offline redo log files to tape.

Archiving to disk and tape cannot be combined during a single BRARCHIVE run.

When you archive the offline redo log files to disk, you may only use the BRARCHIVE options
