Should I > increase it or decrease it? I'm having a hard time understanding what > the doc says for amanda.conf says... As you note, your bumpsize is ignored. The bumpdays parameter gives the minimum number of dumps at each level that must be done before the next higher level is even considered. bumpdays is often recommended to be set to > 1. The rationale being that if you have two level 1 dumps, one could be lost without much concern. But if you only have a single level 1, losing it could be a big problem. I question your multiplier in "bumpmult 4.0". It says to go from level 1 to level 2 the level 2 needs to be 20% smaller than the level 1. But to go to level 3, the size of the expected level 3 dump must be 80% (4.0 x 20%) smaller than the expected size of a level 2. And it will be really hard to get to level 4 as it must be 320% smaller than the expected level 3 (4.0 x 80%). I'd suggest picking a bumpdays with which you are comfortable, get that multiplier down (1.0? 1.2?), comment out bumpsize, then see if 20% gives you what you want, if not start adjusting it. BTW, if you make a specific dumptype for that DLE, you can play with the bump settings in that one dumptype definition without affecting other DLEs. They would be using the global values.

bump* dumptype parameters tuning
Hi, It's with some shame that I must admit that through the long years of using amanda I've never really played with the bump* parameters for DLEs! I'm now in a situation that might benefit from some tuning using those to aggressively encourage bumping the gnutar incremental levels. The drawback of potentially needing more tapes for recovery is not really a constraint for me. I have a DLE (~5TB) for which the estimates are done on the server -- the client, a NAS/filer, doesn't support anything else, so the DLE usage info is really just from the historical usage not the current one. Any ideas/hints on how should I proceed from what is currently (default values I guess) configured? bumppercent 20 bumpsize20480K bumpdays1 bumpmult4.0 Would setting bumpdays to higher values (2 or 3 days) pull in the direction I want to go? Since bumppercent != 0, bumpsize is ignored from the man page, so I guess the only important parameter left is bumppercent. Should I increase it or decrease it? I'm having a hard time understanding what the doc says for amanda.conf says... thanks! jf

Heim, 608-263-4189, jh...@math.wisc.edu I think you are saying don't DON'T want bumping. Bumping is going down to a level-2 backup from a level-1, so as to reduce the amount of data being saved. I think you are saying you only want level 0 backups done. I do this for my "archival" tapes, which should not contain level-1 backups and thus be reliant on some other tape. I use these settings: dumpcycle 0# the number of days in the normal ARCHIVE cycle tapecycle 9000 tapes # some infinite number; always fresh tape for archives inside my dumptype's I include: define dumptype dailyNormal { BDnormal #read in the other file strategy noinc #nothing but full backups; don't even calculate other sizes skip-incr yes } Am I hearing you correctly?

aggressive bump
If I understand the concept of bumpting, then because I'm using virtual tapes, I think I want total bumping to be done -- if there is such a thing. I don't care at all how many "tapes" my backup is scattered over. I inherited my amanda setup from my predecessor in this job and I have never messed with the bump settings. But we are moving from physical tapes to virtual tapes. Here are the current values: bumpsize 500 mb # minimum savings (threshold) to bump level 1 -> 2 bumpdays 1 # minimum days at each level bumpmult 4 # threshold = bumpsize * bumpmult^(level-1) I'm a little unclear on how backup levels and tape cycle interact. It would be fine with me if there was always just one copy of each file on the virtual tapes. -- --- John G. Heim, 608-263-4189, jh...@math.wisc.edu
Re: Does 'force bump' roughly equate to 'strategy incronly'?
There is a planner bug with force-bump when a dle is overdue. The attached patch should fix it. As a workaround, you can set a large dumpcycle (eg. 1). force-bump will prevent full, but it will also bump the level, this might not be what you want. Setting a large dumpcycle and a small maxpromoteday should do incremental without bumping the level.

Does 'force bump' roughly equate to 'strategy incronly'?
One day next week I want to prevent any level 0 dumps, and run only incrementals for that one night. It's not obvious to me from the docs that 'amadmin force bump' will actually prevent amanda from concluding that it's time for a level 0. Would 'force bump' serve my purpose? (My guess = no.) There is more than one runcycle in our tape cycle, and we won't be over-writing the most recent level 0 for any dump. I recognize that changing strategy to 'incronly' for all dumptypes in amanda.conf should have the desired effect, but would prefer to do this through amadmin. TIA. Bryan
The question about the 'force-bump' and the 'force-no-bump'
Hi all I think about the backup schedules as follow: 1st full backup(LV0) 2nd partial backup(LV1) 3rd partial backup(LV1) 4th partial backup(LV1) 'force', 'forcd-bump', and 'forcd-no-bump' each option of the amadmin command had been executed specifying it before the amdump command was executed. 1st $ amadmin DailySet_HD force rh5cli /var/test $ amdump DailySet_HD 2nd $ amadmin DailySet_HD force-bump rh5cli /var/test $ amdump DailySet_HD 3rd $ amadmin DailySet_HD force-no-bump rh5cli /var/test $ amdump DailySet_HD 4th $ amadmin DailySet_HD force-no-bump rh5cli /var/test $ amdump DailySet_HD When the dumpcycle was '1 week' , the backup level was as follows: 1st full backup(LV0) 2nd partial backup(LV1) 3rd partial backup(LV1) 4th partial backup(LV1) But the dumpcycle was '0', the backup level was as follow: 1st full backup(LV0) 2nd partial backup(LV1) 3rd full backup(LV0) 4th full backup(LV0) In this case, is it a specification of amanda that the full backup is executed because dumpcycle is 0 even if option 'force-no-bump' is executed? Your prompt reply would be greatly appreciated. Thanks in advance.

If AMANDA determines that the next > higher backup level will be this much smaller than the current > level, it will do the next level. I see that bump->bump-thing ... will correct that. The basic goal of using these parameters is avoiding too much incremental backups happening too fast. As it gets harder to restore from a backup-set with lev4 or similar as you have to use 5 tapes to get your full data back, you want to avoid lev4 and just go to lev2 or lev3 ... So you want to get some benefit from BUMPING to lev2 (which actually means the switch from level n to level n+1) after you are already on lev1, and this benefit should be saving tapespace because that lev2 backup is smaller than the lev1. Now read again: "If AMANDA determines that the next higher backup level will be this much smaller than the current level, it will do the next level." If size_of_lev(n+1) - size_of_lev(n) > bumpsize, then AMANDA decides to do the lev(n+1), because the savings in space are worth it. Not enough with this, there is also bumpmult ! Actually it's: threshold = bumpsize * bumpmult^(level-1) This introduces a somewhat exponential behavior, bumping from lev2 to lev3 should be harder than bumping from lev1 to lev2, as you want to avoid high backup-levels. There is also "bumpdays" to keep the lev down as well. --- This as a quick-n-dirty-explanation, hope this helps. -- best regards, Stefan Stefan G. Weichinger mailto:[EMAIL PROTECTED]

Prevented bump?
I have a daily backup routine that I have changed around (duh me) and now does not want to complete its daily cycle. I believe it gets stuck on backing up an NT partition using user-tar and compression on the server. Could this be a faulty tape or have I just jimmied something incorrectly? The log says: INFO planner Preventing bump of localhost://ntserver/ppidocs as directed, INFO planner Preventing bump of localhost://ntserver/businesswork as directed. -- Can someone please assist?
