I'm struggling to solve a "dump larger than tape" problem, and not making much
progress. I'm
asking for suggestions and troubleshooting techniques.
I'm trying to back up the Samba share admin//db/f$. I've broken it up into two
sections:
[EMAIL PROTECTED]:~ > amadmin DailySet1 disklist admin //db/f$/
line 82:
host admin:
interface default
disk //db/f$:
program "GNUTAR"
exclude file "./inetsrv/webpub/images/"
priority 1
dumpcycle 3
maxdumps 1
maxpromoteday 10000
strategy STANDARD
compress NONE
auth BSD
kencrypt NO
holdingdisk YES
record YES
index NO
skip-incr NO
skip-full NO

I get this error when backing it up to a DDS-3 tape, which should hold 11.5G,
according to a tapetest run:
NOTES:
planner: admin //db/f$ 20030915 0 [dump larger than tape, 12101907 KB, full dump
delayed]
But, each of the sections is less than 11G:

Therefore, 12.4G minus 5.4G is 7G.
It's like amanda is not taking into account the excluded directories when making the
size estimate,
and then giving up on the level 0 backup because it seems too big.
Here's the info output, if it's helpful:
[EMAIL PROTECTED]:/etc/amanda/DailySet1 > amadmin DailySet1 info admin //db/f$/

Any suggestions on changes or procedures to overcome this problem? I'm getting
desperate; it's just been
making level 1 backups for a week now.
Thanks for all your help and suggestions.
