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) :

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
