NO, it is NOT proper for a "Partial Full Backup"

This is because, as others have already said,

  "amanda does not do partial full backups"


Each DLE receives either a full or an incremental backup.

Re: Partial full backup configuration for amanda

2006-05-31 Thread silpa kala 
Hi,


Thanks for this information. I gone through the all
the threads related to the Partial Full backup
configuration for amanda. 

Partial full backup is happening based on the DLE
entries instead of memory occupied for all DLEs.That
means If one DLE happens to contain 50% of all data,
then one day Amanda must do all that complete DLE at
once (and probably not schedule anything else for a
full dump).  Amanda will not divide the DLE itself.

I seen sometime back amstatus is showing the keyword
"PARTIAL". Is it referring to Partial Full bakup. I
forgot what configuration was done. Please check
whether the following configuration is proper for
Partial Full backup.

Ex : Amanda.conf  -
  dumpcycle 4 days
  runspercycle 4

disklist  -
 sda  path user-tar 50%
 sda0 path user-tar 20%
 sda1 path user-tar 10%
 sda2 path user-tar 20%

sda is backed up 1 day, sda0 is done 2nd day, sda1 is
backed up 3rd day, sda2 is backed up 4th day.
After 4 days it will perform the full backup.Is it
true. Is there any other configuration parameters is
required to perform the partial full backup.

I have little confusion whether skip-full, skip-incr
or strategy parameters need to be enabled for the
partial full backup.Otherwise only dumpcycle and
runspercycle is enough.

Thanks in advance.

Regards,
silpakala

Hi,
 
I need some clarification on the usage of the amanda.

What parameters need to be congfigured for the

dumpcycle 10 days

runspercycle 10
 
Suppose this is the case, the full backup is divided

into 10 parts. That means per day 1/10 of data is to
be backed up. But, Instead of Partial full backup

Not exactly 1/10 of the data, but some number for disklist
entries with total amount as close to 1/10 of the data
as possible.
If you got only 1 entry in your disklist, then there is
nothing to divide or spread.

Also the first time, Amanda tries to dump as much as
will fit on a tape.  It's only during the next runs, that
Amanda can schedule incrementals (lvl > 0) instead of
a full dumps.  You will have to wait at least 1 cycle
before you notice the spread of level 0 over the cycle.


 
Please help me out in this. What parameters need to be

configured in amanda.conf file to perform "partial
full" backup.


I still believe your notion of "partial full" is different
than that of Amanda.




If u provide the example with minimum configurations
or amanda.conf then that will be helpful.


Example configurations are on the wiki:
A minimal one:

Erm, we just had this discussion.  Look in the archives at 
 for a (very recent) thread 
titled "How to Partial full backup".
