First the problem: A Windows fileserver with about 560GB data in 13.500.000 files. (We also have one with 1,1TB data.) Always done (full/standard) incrementals. Consider a security update (local group addition; no discussion about that). A normal incremental backup treats me next run with a full backup of all.
(Server v5.2.4 on W2K-sp4, Client v5.2.3.11 on W2K-sp4) Considerations: - I don't really need or want security on file level: via inheritance the files get the right rights from the directory - A dirsonly backup takes as long as a full incremental (so it seems, and because also file info is sent, doesn't save memory; And about an extra filesonly backup...) - A full incremental takes about a whole night - An incremental with option skipntpermissions treats me with a full backup (that I don't like) next run - An incremental with option skipntsecuritycrc treats me with a full backup (that I don't like) next run (is this a bug or something?) - I don't like full backups at all (except for databases; that why we chose TSM didn't we?) - Journal based backups also need a full incremental now and then Solutions: ?
