Request information on multi-volume backup
Hi, I have a doubt on multi-volume backup. Generally Amanda performs backup capacity same as the media can hold. am I correct? Amanda supports multi-volume tape backup means how many tapes it will support for one single operation. Suppose I am having 4 tapes and each one holds 40GB means total 160GB.Now I want to take the backup for amanda is 150GB; Whether is it supports? If it supports how to configuration for this? What tape_splitsize exactly do? Thanks in advise. Regards, Silpakala __ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
Clarification on source code hierarchy
Hi, I am using 2.5.2p1 version for Amanda. I configured Amanda by executing ./configure --with-user=root --with-user=group. In this case there is no shell script files genereated in sub-directories like amandad-src,tape-src. I executed the make command and found shell scripts are created for amdd ammt in tape-src. It is happening for each sub-directory. Why these shell scripts is required? If don't want to keep those shell-scripts because already executables are present. Shall i delete those creation from the Makefile. What is effect for this? Please help me to understand the source code hierarchy. Thanks Regards, Silpkala __ Do You Yahoo!? Tired of spam? Yahoo!

Hi, I am having one doubt on the source code hierarcy. Can u please give me the details that why two recover source directories are present?

Difference between the amrestore and amrecover
HI, I need some clarification. I worked on amrestore , which we can retrieve the backup image from holding disk or tape. amrestore /dev/nst0 amrestore holdingdiskname But I didn't understand the amrecover.

Source code hierarchy information
Hi,
Anybody help me out to understand the source code.I
given the information what i understood. Please
correct me if I am wrong.
Planner sends the request to the client(amandad)to get
the estimation of the backup data. planner module is
present at server side and amandad service is present
at the client side. Suppose if i am taking the backup
only for the server means DLE has an entry with the
server address. In this scenario the server act as a
client, server bind the ipaddress as a noop,0.0.0.0
and client bind the ipaddress and port no
as 120.120.120.120:10080. {My server address is
120.120.120.120).
Client has the module noop , which provides the
compatibility with the server module.
Client has the module Sendsize which send the
estimated size information to the server.
Planner sends this information to the driver which
initiates the dumper and taper process.
Client has the sendbackup module , which bind the IP
address has 120.120.120.120 with the port no as TCP
unprivileged ports and make the connection with the
dumper has the IP address as 0.0.0.0 with the
privileged port no. Sendbackup connects three port nos
which has to send the backup image, message and index.
Runtar, Rundump module performs the backup according
the program configured as tar ,dump respectively
Sendbackup module send the information to the dumper
through the sockets.
Dumper send the data to the holding disk. Taper reads
the data from the holding disk to the taper. Taper
writes the data to the tape. Here socket connection is
not required between the dumper and taper.
But if the holding disk is too small, then the dumper
directly send the data to the taper, Which uses the
socket connection through the TCP. Because the taper
and dumper is present in the single module. Please
provide what IP address and port no is used to connect
between the taper and dumper.
I have one more question:
Suppose if I want to eliminate the sockets for the
security reason (because of the port no) How can I
approach . Please provide me the details.
Thanks Regards,
Silpakala

Regarding the source code hierarchy
Hi, I am silpakala. I need one help. I want to understand the basic flow of amanda i.e., a. Planner explains about the configuration stuff. b. driver acts as an interface between the planner and dumper/taper. I understood that they are using the socket communication between the planner and dumper. Why it is required. c. Suppose the taper is taking the data from the holding disk to tape. Here Whether the socket communication is required between the dumper and taper. d. What is the noop request. e.Amandad service is connecting to the specific port 10080 in the client side. But the server side which module is directly interacting with the client. Basically i need socket communication between the client and server, where exactly the client is blocking to accept the server connection, Which server module is connecting to which client module, Why the dumper and taper executables are going into /usr/local/libexec (client-specific) directory. Mainly how the sockets are implemented. Suppose if i want to take the backup for the server itself then the socket connection is used for amanda. Is there any way we can elimintate the sockets if we want to take the backup only for the server. please provide the details. Please help me out in this. Thank you very much.

Partial full backup configuration for amanda

What parameters need to be congfigured for the partial full backup i.e.,the full backup is divided into according to the dumpcycle and runspercycle. We configured 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.

Re: Partial full backup configuration for amanda
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.

But, Instead of Partial full backup ,full backup is happening. 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.
