PC-NFS Backups

In v9n248, the question was asked:

Here are the batch files I have been using to backup a local PC's hard
disk to a Sun.  The usefulness of this procedure is that the PC files
copied in this fashion are included on the nightly Sun system backups
(multiple Suns backed up onto a single Exabyte tape).

    REM Do a full backup of C: and D: to host HEART-THROB
    del \backup.log
    echo Full back-up of C: > backup.log
    net use k: \\heart-throb\files\applic\backups\c
    attrib -r k:backup\*.*
    rm -r k:backup
    backup c:\*.* k: /s /L:\backup.log
    c:\nfs\chmod 0777 k:*.*
    net use k: /d
    net use k: \\heart-throb\files\applic\backups\d
    attrib -r k:backup\*.*
    rm -r k:backup
    echo Full back-up of D: >> backup.log
    backup d:\*.* k: /s /L:\backup.log
    c:\nfs\chmod 0777 k:*.*
    net use k: /d

    REM Do an incremental backup of C: and D: to host HEART-THROB
    echo Incremental back-up of C: >> backup.log
    net use k: \\heart-throb\files\applic\backups\c
    backup c:\*.* k: /s/a/m /L:\backup.log
    c:\nfs\chmod 0777 k:*.*
    net use k: /d
    net use k: \\heart-throb\files\applic\backups\d
    echo Incremental back-up of D: >> backup.log
    backup d:\*.* k: /s/m/a /L:\backup.log
    c:\nfs\chmod 0777 k:*.*
    net use k: /d

The above batch files result in the following files and directories on
host HEART-THROB (listing produced using ls -lR /files/applic/backups):

    total 1
