Re: Backup problem

Angie,

The last item on each line of the disklist specifies the dump type touse for the filesystem. These dump types are defined in amanda.conf.Have a look at the comments in amanda.conf to see all the options. Theformat for the disklist is:


  <host> <filesystem> <dump type>

So, to backup the /home/users filesystem on 'myhost', using'nocomp-user' you would use:


  myhost /home/users nocomp-user

as the entry in the disklist.

'nocomp-user' does not have the line:

  dumpcycle 0

'dumpcycle' within a dump type definition tells amanda the maximumnumber of days between full dumps of the filesystem. A value of zerocauses a full backup of the filesystem to be performed every time.

You could, for example, modify 'nocomp-user' to read as follows andleave your disklist as it is:

define dumptype nocomp-user {
    comp-user
    comment "Non-root partitions on slow machines"
    index
    program "GNUTAR"
    compress none

      dumpcycle 0  # <----- force full backups

What's mean by "nocomp-user" in disklist then?
Please advise.  Thanks.

From my understanding, you should be able to do something like the

following:

  fs3 /vol0 always-full
  fs3 /vol1 always-full

The dump type 'always-full' is defined in your amanda.conf already:

define dumptype always-full {
   global
   comment "Full dump of this filesystem always"
   compress none
   priority high
   dumpcycle 0
}


The 'dumpcycle 0' line tells amanda to always do a full dump of the
filesystem.  This dump type does not use compression.  We have a new
dump type here which uses compression and does a full dump, defined as
follows in amanda.conf:

  define dumptype high-tar-full {
    high-tar
    comment "high priority, full dump with compression"
    compress client fast
    priority high
    dumpcycle 0
  }

This makes use of 'high-tar', also in your amanda.conf already.

You ould then put this in your disklist:

  fs3 /vol0 high-tar-full
  fs3 /vol1 high-tar-full

You will need gzip and tar installed on your machines.

Hi James,

Thanks for your prompt reply.

The dumptypes are :

fs3 /vol0 nocomp-user
fs3 /vol1 nocomp-user

Would you please advise how to force amanda to do the full back-up every
night?

Thanks.

BR,
Angie
