Normally I would set up with weekly tape group rotations and Daily pools so that for a work week, I would have maybe 3 tapes for each day and more tapes for the full backup on Fridays. I would also have things like
Volume Retention = 17d Volume Use Duration = 2d Maximum Volume Jobs = 4 to allow for tapes not inserted on time (Volume Retention slightly less than 3 weeks, etc.) Now I am considering a monthly group of tapes with maybe 3 groups of rotating tapes and that causes me all sorts of confusion with the ideal setup. I have an LTO-4 tape w/ changer so I am dealing with groups of tapes for each rotation. My thought is that the first backup for each cycle would be a full backup. Then the rest of the month would be an incremental backup. I think I could probably use maybe 61 or 62 days for 'Volume Retention', maybe 29 days for 'Volume Use Duration' and some very high number for Maximum Volume Jobs so that each workday's incremental could just keep getting written to the same tape until it fills. I think my questions are: - If I target the first day of the month to start a new rotation for a set of tapes, this date may come over a weekend or a holiday but I gather I can set the 'Maximum delays' to an appropriate value but is there a better way to handle this? - How can I ensure that the previous months tapes status is changed to 'used' so that bacula doesn't ask for a tape from the previous month? - Do I have to segregate the 'Pools' for each monthly set of tapes? Is there any reason to segregate the 'Pools' for those that are Full or Incremental backups when I want to keep the entire month together as a group for swapping in/out of the changer? - Does this seem correct...
