I cron trim my rdiff-backups to 3, 6 or 12 months depending on which partition (directory whatever) it is. You then need to decide on backup frequency - it may vary from minutes or hours to daily .. again depending. I run key backups every 1 to 2 hours and otherwise nightly. The cost of hourly's is low if the change volume is not too rapid. gene -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
