AMANDA Version: 2.5.2p1
AMANDA Server: Solaris 10 Sparc
Normally I run my backups at night but yesterday I had to run it in the day
and was noticing that size estimate part was taking a very long time to run.
Looking at the amdump file I see the following: ³planner: time 18363.178:
getting estimates took 18362.848 secs² which is 5 hours.
I also noticed that no backup started before the the last estimated
completed. I assume this is normal.
I want to see if there is some way to cut the estimate size time down or see
if maybe I am doing something dumb.
How I do things.
Before each backup
1. I run a program that gets a list of all the home directories that
begin with each letter of the alphabet and places them in a file called
³/local/Amanda/UsersList/users-?². Example auser1, auser2, auser3 , will be
in the file /local/Amanda/UsersList/users-a and buser1, buser2, buser 3 will
be placed in file /local/Amanda/UsersList/users-b and so on for each letter
of the alphabet.
2. I do a fssnap of the users file systems which is
/export/fssnap/users.
3. I them run amdump.
A snippet of my disklist looks like the following.
zorn /export/users-a /export/fssnap/users {
users-tar
include list "/local/Amanda/UsersList/users-a"
}
zorn /export/users-b /export/fssnap/users {
users-tar
include list "/local/Amanda/UsersList/users-b"
}
:
:
In the above case all the users are on the same host as the amanda server
and I use the default ³client² to do the estimate and I use tar to do the
backup of the users. I have to do the fssnap and I have to use tar to do the
backup of user data.
QUESTIONS:
1. How does the estimate work when using an include list. Does it have
to go to each user directory in the include list and figure the estimate
size for all the users in /local/Amanda/UsersList/users-??
2. I was thinking about using the ³server² estimate for the users in the
include list to try and increase the speed of the backup. Our user
directories do no change that much so I think I am ok in this area.
3. Any other suggestions on how to cut down the time it takes to get
estimate size?
Thanks
Robert
