Environment

Software Prerequisites: Before you can install COSbackup 3.2.6 (application), COSmanager 4.2 (or newer) must already be installed on the same host.


Notes (only applies to patch)

Patch applied after COSbackup 3.2 has been configured: If you are using, or choose to use appending backups, you must change the label type for each media type used from “COSstdtape” to “COSstdindx”.

To change media type:

  1. Select Media from the COSbackup button bar.
  2. Select Maintain > Media type.
  3. Select a media type to change, then select Maintain > Change.
  4. Change label type from “COSstdtape” to “COSstdindx”.
    Label type
    This determines what label format and method will be used to electronically label volumes:
    COSstdtape
    writes a short file containing the media number and ‘date last written’ to the start of the tape, but does not write an end-of-data marker.
    COSstdindx
    writes the label to the start of a tape, and an end-of-data marker after the last file.
    end_label
    writes the label to the last block of a diskette.
    sV_ filesys
    System V filesystem label using the labelit command.
    blank
    volumes will not be labeled.
Press Accept to save this media type information.

If any of your media types have a label type of “COSstdBOT”, please call the Functional Support Line.


Patch applied after COSbackup 3.2.1 patch applied: No further action required.


Patch applied after COSbackup 3.2.2 patch applied: No further action required.


Patch applied after COSbackup 3.2.3 patch applied: No further action required.


Patch installed same time as COSbackup 3.2: No further action required.


Technical Notes: Using COSbackup V3.2.6

This section contains some technical notes, tips, and troubleshooting information to help you when installing or upgrading to COSbackup V3.2.6. Detailed information on setting up and using COSbackup can be found in the Backup3G User Guide V3.2.


Arbitrary commands can easily be run as part of a backup job

The scan method now defaults to multi-volume media scan, where the scan proceeds from the last tape in the set to the first.

To manually scan a single volume from the command line, you can still use the command:

code FSdrive <drivename> scan


Media scan now default to multi-volume

The scan method now defaults to multi-volume media scan, where the scan proceeds from the last tape in the set to the first.

To manually scan a single volume from the command line, you can still use the command:

code FSdrive <drivename> scan


Media copy now run from ‘At-end command’, COSbackup interface or command line

There are now three ways to produce a duplicate set of a backup media volume set. In all cases the target drive must be of the same media type as the source drive.

  1. From the At-end command as defined for a backup job:
    FScopy [-u] [-U] [-T <minutes>] [-r <retention>|-r <days>] <target drive>
    This will copy the media set used for the current backup to a new media set in the target drive. The expiry date of the duplicate set is set to the same date as that of the backup job. This can be overridden by specifying “-r <retention>” or “-r <days>”.

    If the target drive is likely to be busy when needed for creating a duplicate media set, a timeout parameter may be added to the above command, “-T <minutes>”. If this parameter is omitted and the target drive is busy, the media copy will fail.

  2. Via COSbackup interface, from the COSbackup button bar:
    Media > select media set > Maintain > Copy

    You will be prompted for the run mode, the source drive and the target drive. The retention defaults to that of the selected media set, but may be overridden.

    When using manually loaded drives, unless the output media volume is preloaded in the target drive, a “Change media” will appear on the backup job monitor. To preload a scratch media volume, from the COSbackup button bar:
    Drive > select target drive > Operations > Load scratch

  3. From the command line, as would be used by COStask or COSduty, or a 3rd party batch processing product:
    FScopy -b [-u] [-U] [-T <minutes>] [-r <retention>|-r <days>] -s <media number> <source drive> <target drive>
    The retention period must be defined in the retention table. If it is not, the retention of the duplicate set will be set to “forever”.


Restore steps may now be pre-configured

You may now initiate a restore via the command line. This may be used by COStask or COSduy to preconfigure specific application restores. The command is:

code FSrestore -i|-b [-D <to directory>] [-h <to hostname>] [-v <drive>] [-M <method>] [-f <files>] [-d <directories>] [<media number>]

If any parameters are missing a prompt will be displayed requesting the missing values.


Warnings

None known.


Hardware and OS Dependencies

AIX 4: cpio backup methods do not backup files greater than 2 gigabytes

The /usr/bin/cpio program, as used by COSbackup, cannot backup files that are greater than 2 gigabytes in size. The standard cpio header uses a 32 bit signed type to store the file size. this limits the file size to 2 gigabytes minus 1 byte.

Appears: “< filename > ?” is displayed in the backup log, when attempting to backup a file greater than 2 gigabytes in size.

Linux: cpio backup methods do not backup files greater than 2 gigabytes

Appears: “filename is too large to archive in current mode” is displayed in the backup log, when attempting to backup a file greater than 2 gigabytes in size.
