Some dumps may have been left in the holding disk. Run amflush to flush them to tape. The next tape Amanda expects to use is: intra This feature is only available to subscribers.

Know that this does not necessarily mean magnetic tape.
Amanda supports backing up to hard disk via the file driver or even a RAIT feature, which could be multiple tapes, multiple hard disks, or a combination thereof.
Important Terms When talking about any subject, it's good to have a common vocabulary. Below are some important terms that should be understood. Level 0 A full dump, or back up, of a set of files. This means that every file is saved for later retreival. Level 1 The first incremental back up of a set of files. This means that only the files that have changed since the last Level 0 have been stored for later retreival. Level n The incremental backup of files since the last Level n-1 backup.
Note: Levels can sometimes be difficult to understand, so there is an Example available. Usually 1 week runspercycle The number of times during a dumpcycle that Amanda will be run. Usually 7 for every night of the week or 5 for every weeknight, assuming a dumpcycle of 1 week tapecycle The number of tapes Amanda must use before "recycling" tapes.
The answer is: "Does your Operating System Support it? It depends on Operating System utilities such as dd , tar and the many flavors of dump to do that. Run the following commands to setup the hostname of your Amanda backup server. Make sure that you are connected to the Internet for installing updates and Amanda server packages. Run the following command to update your system with latest updates and patches.
Once your system is updated you can start the installation of Amanda Backup Server using 'yum' command as its packages are available its default EPEL repository. Go ahead by running the following command and press 'y' key to proceed its installation including its dependencies. Amanda will be executed by xinetd, so we need to install this along with some of its required packages for Amanda on the system.
Let's start the 'xinetd' service using the command as shown below. First we will make some directories uisng the root user, but make sure and confirm your Amanda user, that probably "amandabackup" or "amanda" or "backup", depending on how you installed Amanda.
We are using the default 'amandabackup' here to assign the ownership of the following directory structure. Now, we are going to add an 'amanda. Lets open this configuration file using your best editor and put the following contents in it. Keep in mind that you should edit 'dumpuser' appropriately if your Amanda user has another name. There are a number of configuration parameters that control the behavior of the Amanda programs. All have default values, so you need not specify the parameter in amanda.
Next, we will add a 'disklist' file with a single disk list entry DLE. The 'disklist' file determines which disks will be backed up by Amanda. The file contains includefile directive or disklist entry DLE. General usage was to describe a DLE as a partition, or file system. Save and close the file using ':wq! So, we have done the configurations let's move to the next step. Amanda has a nice utility called 'amcheck' which can check a configuration for you.
Running it on to test configuration that gives you the results of your configurations. Note that almost all Amanda commands take the configuration name as the first argument like in our case it is "MyConfig". Amcheck runs a number of self-checks on both the Amanda tape server host and the Amanda client hosts.
On the tape server host, amcheck can go through the same tape checking used at the start of the nightly amdump run to verify the correct tape for the next run is mounted.
