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_dir
Required value: A directory in which the offline redo log files should be backed up.
This is generally only required when you are working with a two-phase backup 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 backing up to tape and for restoring from the tape to the disk, if this become necessary in connection with a recovery.
Only use BRARCHIVE backing up to disk in the situations mentioned above. In all other cases, always back up the offline redo log files to tape. Backing up to disk is not a substitute for backing up the offline redo log files to tape.
You cannot combine back up to disk and tape during a single BRARCHIVE run.
When you back up the offline redo log files to disk, you can only use the BRARCHIVE options -s, -sd and -ds.
