I am running Amanda 2.5.0 on a Solaris 10 host. This is the first time I have tried the tape_splitsize to backup a large filesystem.

My dump type looks a follows:
define dumptype users-tar-span {
global
comment "backup of users using tar with spanning"
program "GNUTAR"
tape_splitsize 30 Gb
maxdumps 10
exclude list "/pkgs/amanda/etc/amanda/exclude/user_exclude"
}

In /var/amanda/archive/amdump I have

taper: r: end zorn./export/fssnap/users.20060425201728.0 part 6064, splitting chunk that started at 62085120kb after 10208kb (next chunk will start at 62095328kb)
taper: reader-side: got label archive:000068 filenum 6066
taper: r: end zorn./export/fssnap/users.20060425201728.0 part 6065, splitting chunk that started at 62095360kb after 10208kb (next chunk will start at 62105568kb)
taper: reader-side: got label archive:000068 filenum 6067


QUESTIONS:

1) The above log seems to show that the tape_splitsize is 10G and not the 30G that I indicated in the tape_splitsize. Is this correct? Other than the tape_splitsize what other parameter do I need.

2) My backup was running slow and and noticed that zorn./export/fssnap/users was not in the HOLDING DISK so it must be reading the backup directly from the disk. My holding disk is 200GB and the filesize that I am backing up is 325GB. Do I need to have my HOLDING DISK size as large as the file system that I am backing up using the tape_splitsize.

Thanks
