Re: Backup and restore question
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.

Re: Backup and restore question
Hi Robert, I think that -incremental and –deletefiles are not available (or ignored) with -imagetofile. It makes sense since -incremental would lead to a file restore whereas -imagetofile leads to a bloc restore. You should note that –deletefiles is not availbale (or ignored) if your backup has been done like you do : backup image F: -mode=incremental -- Best regards / Cordialement / مع تحياتي Erwann SIMON - Mail original - De: Robert Ouzen rou...@univ.haifa.ac.il À: ADSM-L@VM.MARIST.EDU Envoyé: Mercredi 17 Juin 2015 11:57:18 Objet: Re: [ADSM-L] Backup and restore question Hello Ronald Make sense ….
