Robert,
You cannot perform a normal incremental
once you have performed a full image, unless you have two separate nodes,
one doing image backups and one doing file by file backups. You can
do incremental image backups but not an file by file incremental.
Best Regards,

Hello Erwann
I admit I am quite lost .....
I run a regular incremental backup on disk F: (first time , so like
full backup)
As: INC F: -su=yes
I run a full image backup of F: as: backup image F:
But if I run after a backup image with -mode=incremental got error:
tsm> backup image f: -mode=incremental
ANS1813E Image Backup processing of '\\nasw\f$' finished with failures.
ANS1229E MODE=INCREMENTAL is not valid on \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy17.
Image backup not processed.
I erased everything an made a test without doing a regular incremental
backup of disk F as shown below:
tsm> backup image F:
Image backup of volume 'F:'

Of course NO data in the -mode=incremental but NO error ????
What is the correct sequence to have combination of regular incremental
backup and iimage backup ??
Thanks again for the advice
Best Regards
Robert

Hello Robert,
The –deletefiles flag won't be an option if you don't run regular incremental
backup which is able to mark deleted files as inactive.
The -mode=incremental flag uses incremental by date method that does not,
so TSM DB is not aware of file deletion.

Hello Erwann
I need a little bit more explanations.
if I understand correctly ,I need to do;
1. backup image E:
(full backup)
2. backup image E: -mode=incremental
(only new files are backup , fast backup
I want to use (test) the restore with option imagetofile
Restore image E: F:\diskE.iso -imagetofile -incremental
–deletefiles
So NO need for regular incremental backup ???
T.I.A Best Regards
Robert

Hello Robert,
Backup image is a full image done at block level. When specifiying mode=incremental,
il a file level incremental that is done : only files having a modified
date later than the previous backup image are backed up.
The -deletefiles flag when restoring an image backup is only to be used
when backup of the same volume is done twice : block level (image backup)
and file level (regular forever incremental).
See this excellent presentation (from slide 28) :
http://tsm-symposium.oucs.ox.ac.uk/2007/papers/Andy%20Raibeck%20-%20Potpourri%20du%20Backup.pdf

Objet: [ADSM-L] Backup and restore question
Hi to all
Question for people using BACKUP AND RESTORE IMAGE
I have a Windows client with millions of files and I am thinking
of using backup image on it.
Some questions , after the first backup image of disk E: (full
Image) as : backup image E:
In the documentation I can use after it and incremental backup image as:
backup image E: -mode=incremental CORRECT ?
Of course the content of disk E: will change, files will be added and deleted.
So the correct syntax for restoring the image will be: Restore
image E: X: -incremental –deletefiles
Any advice will be appreciate
Best Regards
