backupios -X (auto expand /tmp space) option , same as maksysb/savevg on AIX

The backupios command returns error when one or moer Non-rootvg storage pool configured. But mksysb looks O.K. This would be "working as designed" but always troubles me.

example:
-----
$ backupios -tape /dev/rmt0
Creating information file for volume group datavg.
Creating list of files to back up.
Backing up 36 files.backup: 0511-432 A write error occurred: There is not enough space in the file system.
backup: 0511-079 The backup media may be damaged.
Use a different disk to run the backup.
0512-005 savevg: Backup Completed.
The backup command completed with errors.
The messages displayed on Standard Error contained additional
information.
Not able to save structure for Volume Group "datavg".
Backup in progress. This command can take a considerable amount of time
to complete, please be patient...
102327 of 102327 files (100%)
0512-038 mksysb: Backup Completed Successfully.
------

It looks like some kind of temporary storage shortage (/tmp?) On AIX, mksysb/savevg command have "auto expand" (-X) option but VIOS do not have equivalent. It would be more consistent if backupios has -X option also.

    Thank you for your feedback. I am using 3.1.3.10 at this moment. I will try after next scheduled update (to 3.1.3.20.)

    Problem statement:
    As per the given example, the rootvg backup by mksysb command is successful but the datavg backup by savevg command is not successful.

    Observation:
    savevg attempts to save the datavg in /home/ios/vgbackups and is not successful because /home was low in space.

    The displayed error "Backing up 36 files.backup: 0511-432 A write error occurred: There is not enough space in the file system."
    is for /home.

    So the RFE requirement to have an option to increase the /tmp space is irrelevant since the problem is with /home being low in space and not /tmp.
    If we want to increase the size of /home at run time for successful backup of datavg, then the underlying savevg command should provide a way to increase the /home. (Currently savevg has -X for increasing the /tmp)

    Proposed Solution:
    I can open a defect against savevg to comment if the above solution is feasible.

    Let me know your thoughts and inputs.
    Awaiting a reply.

    Thanks,
    Ruchira.
