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):
