Regular Expressions and disklist
I want to know if it is possible in a disk list to specify multiple directories on one line using regular expressions like so ./NL-SFS3-02[4-7] so NL-SFS3-024 NL-SFS3-025 NL-SFS3-026 NL-SFS3-027 Craig Hancock
Include and Exclude list
Is it possible to setup in include list like so ./NL-SFS3-02[4-9] ./NL-SFS3-03[0-2] And only include these directories meaning if they aren't any fo these directories don'ttry to back them up. Craig Hancock
time limit and holding disk
I want to know if it is possible to have a time limit set during a backup meaning. scenerio Backup starts at 11:00 pm and stop at 6:00 am If the bacup wasn't complete then resume then next day at 11:00 pm. If this is not possible how can I set have it dump to holding disk and stay in the holding disk and I will dump to tape when it is convient.

There has been alot of discussion lately on how to use
RAIT. I have attempted to setup rait on my site and I haven't had
much success.
I have and AIT-3 Overland library system that can hold 38 tapes.
My setup is like this I split the library system in have the first 18
slots and its drive belong to a certain number of hosts. The other
half is meant for one host ane one host alone.
The first have uses one tape device and the chg-zd-mtx tape
changer and that works well. When I tried to configure RAIT
with chg-manual I am getting prompted to insert tapes that are
already in the library.
Here is an example

Re: New tape nonsense
John please forgive my assumptions. But I still don't understand. If tapecycles are defined by number of tapes. How is possible to double runspercycle if its meaurement is in weeks. *Relizes that he will get slammed for this but still confused* Craig Hancock > In another posting you asked about why it is recommended that tapecycle > be at least 2x runspercycle.

If I understand this correctly once a tape goes through an entire tape cycle it will be overwritten. So say a tape with 100G capacity has 60 gigs on it. If my tapecycle was at 4 weeks then when the tape in question is loaded after 4 weeks does amanda start at the point were the tape is meaning the last track it left off on or is the taped rewind. SO (and this is just an observation) after the dumpcycle is done the best practice would be to offload your tapes offsite.

Well I put 4 weeks because it was preposed that we do a full backup once a month. The amount of data that I am dealing is 2.1TB If I understand you creectly if I shorten it to something like 1 week then it will be eaiser forme to do a restore.

If I choose 7 then your right I am going to have to strech it out but I am not sure how to do this. With the size of data that I am dealing with this will seem terribly complicated.

What do you mean play catch up with that for one dumpcycle or maybe two. Forgive me lack of sleep but the Sentence starting with Watching the tape usage is confusing. Your scenerio states you have a 46gig drive and that your full backups is about 2gigs in capcity is that accurate.

Re: New tape nonsense
> "tapes in my library are not full" is not a useful thing to say about > amanda; amanda over-writes each tape, *never* appends. > This message was from a previous message sent by Jay. I understand that amanda doesn't do appends of backups. However I wasn't aware that a complete backup get overwritten. The reason I ask this is because I thought that during backup you have a brand new tape. If your first full backup excceds the capcity of the tape amanda will report the area and amanda will rewind the tape to the begining of the tape. So say if you have a tape with a few backups on it if the next backup exceeds the capcity of the tape then is the statement above saying that once preexisting backup reaches the end of the tape then will amanda rewind the tape and write over the old backups?

New tape nonsense
Hello all I have a Overland Library AIT-3 system that holds 40 tapes. I split the library into 2 configs. One config has 20 the other has 20. I have been runing my tape library system sense august. I am now at the point were amanda is request a new tape. I interpret this message as All the tapes you have in your library are full please use a new blank tape. But I know for a fact that all the tapes in my library are not full meaning I have more space to put on them. Also in my tapelist file each tape is marked to be reused so I don't understand why it wants a new tape. If anyone one can shed any light I'd greatly appriciate it.

Questions
After much experimentation I have finally succesfully created an amanda backup. But I have not been able to figure if these features are possible. 1) I currently have enabled 4 dumps at a time. What I understand this meaning is the option inparallel does 4 cleint dumps at a time. If I have a disklist of 18 disk does that mean that all 18 disk get backed up to one tape or does that mean that every 4 disk get backed up to tape. 2) When sendszie is executed to estimate how big a directory or disk is is it possible to have sendzie work with the process that dumps to tape to judge if a directory is to big for that tape and load another tape for that backup 3) Is it possible just to do fiolesize estimateions before issueing amdump. What I am trying to accomplish is to do estimations and have amdump pick up were it left off to save time. 4) In regards to number 1 to elevate this problem I have been doing amdump "configureationname" partition. I am doing this for each disk in my disk list is it possible to have certain disk go to one tape and then push otehr disk to go on the second tape.

changer.conf
I am just curious all the people that use amanda on this list what changer do you prefer. I am currently using chg-zd-mtx, but highly thinking about changing my problem is this I am trying to create 2 configs one setup for directories that don't change very much and another config for directories or host that modifiy data alot. So since I ahve a 40 tape library unit with 2 tapes inside it. I split the library in half( for now) and use one tape drive for each config. When I specify the first slot in my changer.conf file on the second config it seems to always load the tape in slot one and not in slot 19 and I don't understand why. Any thoughts or suggestions would be appricated Craig Hancock -- -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 -BEGIN PGP SIGNATURE- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE9P+Y5awsElDuSDs0RAgxoAJ40NBfXWSP5dwsRK6AWZRXP6fNm+wCgpWf4 MwLEwsq3TDVGR8ntq3+w65k= =qTeY -END PGP SIGNATURE-

Backing the backup server
I am trying to backup the backup server in amanda and I am a little confused on how to go about it from the documentation you setup a .amandahosts file on the server and the client. Is an entry for the backup server need to be there. If so what should the connect as user be 1) amanda 2) root If this is not the case then how does one configure the backup server?

disklist and sub directories.
Hello all after playing with amanda all week I have finally gotten into a situation were my entry in disklist file is to big. From what I've read amanda isn't smart enough to pick were it left off if it ran out of tape it will attempt to start from the begining again. Because of this I was thinking of making of these disklist. Origianally I have a disklist of /home/data but unfortantely is is 92G but tape can't write a complete 92 gigs. So I was thinking of spliting this in 3's 1) /home/data/directory 2) /home/data/directory2 3) /home/data What I would like is to do is backup 1) and 2) seperately, but once we get to 3 I don't want thost 2 directories to be backed up from disk 3 Now is this possible.

sendsize
Is it possible to to run sendize and then run amdump later. I have filesize directory that is extremely large and I want to perform the estimation first and then on another day I actually want to flush to tape is this possible. Craig Hancock
