Weird dumpsize problem (symlinks??)
all,
I have got a weird problem and cant figure out whats wrong.
I get an error during a dump:
FAILURE AND STRANGE DUMP SUMMARY:
lalalalala /samba lev 1 FAILED [dump larger than tape, 10101550 KB,
skipping incremental]
so that means its 10.1GB, correct? (The tape is only 4/8gb, but thats not the
questions here).
Yet when I do a du -s . inside that /samba directory:
[EMAIL PROTECTED] /samba] #du -s .
5.3G.
Thats HALF of what amanda is trying to backup!
I have no idea where the 5GB comes from amanda is trying to dump.
Does Amanda follow symlinks? I thought it does not!
I have two symlinks in there, which COULD encount for the incorrect sizes:
[EMAIL PROTECTED] /samba] #find -lname * -exec ls -la {} \;
lrwxrwxrwx 1 root root 6 Oct 8 17:20 ./Shares/SysAdmins/home - /home/
lrwxrwxrwx 1 root root 16 Oct 8 17:20 ./Shares/SysAdmins/Profiles -
/samba/Profiles/
I use these (if I am on a windows box and logged in as SysAdmin)
to fiddle with users profiles or with users home directories.

Listing a tape content ?
Is there an easy way to list the content of an amanda tape ? I'd like to have the file / directory names and the last modification dates of the files. Thanks

Up until now there have been no issues and the backups were easily fitting on the tapes. However lately the datasize is going above 100Gig and for some reason Amanda is reporting it has reached the end of the device even though it is a 200G native tape. Are you sure your drive and tapes are LTO-2? I'm using LTO-2 with hardware compression off, and I routinely hit EOT around 206 million KB.

Don't understand what's happening specifying Samba shares to amadmin find
I don't understand what's happening when I try to specify Samba shares on the command line: [EMAIL PROTECTED]:~$ amadmin DBackup find centernet Scanning /dumps/amanda2... Scanning /dumps/amanda...

Hello, Is there a way to backup backup server after all the others server and not in the same time ? I have perf issue because the backup server is backed up in the same time as the other servers ?

Typically that might be 4 - 10 hrs total. If your run is going much longer I'd guess you did not use the estimated length option on your command line. -- Jon H.

Re: tapetype HP ultrium 3 ?
Yes, I just read about it and I also disabled HW compression. So now : amtapetype -o -e 400g -f /dev/nst0 thanks again Jon LaBadie wrote: On Mon, Oct 24, 2005 at 12:27:34PM -0400, FM wrote: Thank you for the reply, I'm using amtapetype for 3 days now to have the right info, I'll post on the amanda tapetype list If you mean you have been running a single instance of amtapetype for 3 days, abort it right now.

How about specifying not before cron-start-time + 1 hour for everything *except* the backup node itself?Force it to be the first one.It is easier to estimate how long one node will take,than how long all the rest of them will take. Of course, that means specifying a starttime for all nodes but one. Deb
no backups M-T?
Hi, I just got my tape library back online, and I thought backups should be good to go now, but it seems that maybe all those days that i missed out on backups have confused amanda or something. No backups occured over the weekend (I had changed my crontab to make it run 7 days a week), but I didn't get any emails from amanda over the weekend. I tried running 'amadmin DailySet1 balance', and it reports the following: due-date #fsorig KB out KB balance -- 10/24 Mon0 0 0 --- 10/25 Tue0 0 0 --- 10/26 Wed0 0 0 --- 10/27 Thu0 0 0 --- 10/28 Fri 20 182596290 182596290 +362.5% 10/29 Sat6 62085930 62085930+57.3% 10/30 Sun4 31671340 31671340-19.8% -- TOTAL 30 276353560 276353560 39479080 (estimated 7 runs per dumpcycle) How come there is nothing scheduled for Monday-Friday? My crontab is set back to running amanda Monday-Saturday (does this utitity even read the crontab? I'm not sure how it works). Anyway, I flushed the old backups (from last week) to tape w/ no difficulty, so I think it should be able to dump stuff to tape... I'll run amdump manualy tonight if i can't figure this out, but it would be nice to figure this thing out. Thanks! Cameron Matheson

You probably want to check your dumpcycle, runspercycle and such in the amanda/Dailyset1/amanda.config to make sure its doing an every day mode. Although, I note that the above does indicate you do have a dumpcycle of 7 days, and a runspercycle of 7 also. So now I'm scratching my head too. And coming up empty unforch. Thanks!

Read up on amanda for a background so that you can come back to the list and ask more meaningfull questions.

RE: Listing a tape content ?
It depends on how you backed up your disk. Assuming you're using GNU tar, you'd want to do something like this: amrestore -p /dev/nst0 server-name disk | tar -tvf - That pipes the output of amrestore through tar which just displays the contents.
