Hi again >From what I gathered I will more than likely go with labelling 22 tapes for 2 week cycle not including weekends and 12 DAT DDS-4 to pull out at the end on the month. When I pull the monthly tape i.e daily14 out can I just label a replacement tape daily14 as per the pulled tape or must I use a new name.

The whole extra config should live in a seperate directory, such as /usr/local/etc/amanda/monthly. You'll have to manage the tape loading schedule so that the tape you have labeled for the monthly usage is loaded at the proper time, and that the daily tape is not loaded. You may, because of scheduleing snafu's that will happen (the question isn't if, its when) want to have seperate holding disk areas specified so that if the tape isn't loaded, it can still do the backup and you can load the right tape and amflush it later when you've discovered the error. I do not do that here as its rather hard to remove a virtual tape when I haven't a working tape drive. I've found that a utility 200GB hard drive with virtual tapes is for me, considerably more dependable than DDS2 tapes and the drives that went with them ever were. Had I been willing to spend 5+ grand on a newer technology drive and its tapes, that probably would not be true. However, if I really had 5 grand to spare, I'd upgrade my 88 Nissan 4wd pickup, red cancer is going to keep me from getting it inspected one of these days, and at 201k miles its now leaving small puddles of 5w30 on the driveway. Old farts (I'm 70) with limited incomes tend to think a bit more about practical things. :-) -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Hi Again Thus continue and labelling DailySet101 - 110 as So far, to Dailyset 122 Thus end of each month pull that tape and carry on as usual.

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. Just some ideas. jl -- Jon H.

Re: I am correctly concluding I need only a tapecycle of 10 tapes - Using 10 tapes for fortnightly backup scheme.
Hi Great Yes I am going to use 10 tapes in total and reuse the first tape after 10 week days worth of backups. Thus is it fine to pull the last Friday tape at the end of the Month for archiving and then re-label the tape I pulled. Thanks I am nearly there .

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. -- Jon H.
