Re: Using 10 tapes for fortnightly DailySet backup scheme and for a Monthly Config 12 tapes.
Chuck on closer thought dumpcycle will need to be zero as the config assumes one run per day - ie the dumopcycle is really per invocation of this config, and doesn't count actual days -- Martin Hepworth Snr Systems Administrator Solid State Logic Tel: +44 (0)1865 842300 Chuck Amadi Systems Administrator wrote: Hi again If I run a Monthly config #'sudo -u amanda crontab -e # Backup check running amcheck at 4.30pm on the 2nd day of each and every month. 30 16 2 1-12 * /usr/sbin/amcheck MonthlySet1 Thus use 12 DSS-4 DAT Tapes and set the Monthly amanda.conf as below dumpcycle 4 weeks # the number of days in the normal dump cycle runspercycle 1 # One run per month tapecycle 12 tapes # the number of tapes in rotation 12 per Year.

Thus every fortnight. I am correctly concluding I need only a tapecycle of 10 tapes I hope to pull out the last Friday tape in that Month to archive and thus label another tape to replace it. Here's my config file. dumpcycle 0 weeks # the number of days in the normal dump cycle runspercycle 1 # the number of amdump runs in dumpcycle days # (4 weeks * 5 amdump runs per week -- just weekdays) tapecycle 10 tapes # the number of tapes in rotation # 4 weeks (dumpcycle) times 5 tapes per week (just # the weekdays) plus a few to handle errors that Think of tapecycle as how many "different" tapes amanda must use before it will reuse the first one. In your setup, it looks like full backups every run, tapecycle is as critical as a setup doing mixed full and incrementals. Set it to whatever you want, or are comfortable, having amanda not overwrite before being allowed to reuse. If you want the last 10 full dumps to be sure to be around, then set it to 10. If the last 5 is comfortable, you can set it to 5, but still use 10 tapes. Amanda will only check that at least 5 are still the most recent. I just want to make certain I'm not confusing your intent because of terminology. You want to "pull" the monthly tape and "relabel the tape you pulled". That second part (relabelling) is a different tape, right? If so, it is not "relabelling" but just an initial label for that tape. Now, if you mean to use the same label as the one pulled, think twice. Amanda keeps indexes of what is on a tape. If you use the same label as the pulled tape, then you will soon lose the index for the pulled tape (when the new tape is used). Instead, when you pull a tape, mark it a "no-reuse". The index will be retained. But the new tape will need to have a different label. In fact, you could label up 22 tapes, 10 for cycling, 12 in anticipation of pulling monthly for a year. Your tapecycle could be set to 10, and you could cycle through your first 10, or all 22. Amanda will still ensure that the most recently used 10 are not overwritten. Monthly, just pull whichever of the 22 was used. You will have a "hole" in your tape cycle, but amanda won't care. But maybe the human (you) will :)) If so, set your label scheme up to be something like DS-xx.y where xx is your ordering sequence and y is which replac- ment. Maybe you label up DS-01.0 to DS-10.0. At the end of the month, say you have to "pull" DS-05.0 Mark it as no-reuse and label up a new DS-05.1. This preserves your ordering and tells you it is a tape not in the initial cycle. Might be important for some tapes (eg. DAT) which have a fairly short life.
