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 -- Best regards / Cordialement / مع تحياتي Erwann SIMON ----- Mail original ----- De: "Robert Ouzen" <rou...@univ.haifa.ac.il> À: ADSM-L@VM.MARIST.EDU Envoyé: Dimanche 14 Juin 2015 04:47:33 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 Robert Ouzen Haifa University
