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

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
