Ok but let's simulate a crash in your example: On day 2, before the incremental backup, the filled one (day0) is lost. Is backup made on day1 still available with "all" files or only with the latest 5GB added between day0 and day1 ? ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
