Table of contents
The Storage page lets you select and configure target devices for backup. Once configured, a device can be then bound while creating a backup set on the backup set page.
Storages Page Overview
Below table shows, the devices associated with different AE Servers. One device can be associated with one or more servers.
Storage Device Type is the type of the storage device; existing devices can be filtered/sorted based on the type.
Device Name is the name of the device as specified on the Admin Devices page.
Associated Server: A Storage device should be associated with a Server. Cloud Storage devices can be associated with more than one server.
Status shows the status of the Storage device.
A green checkmark means the device Active on all the servers that are associated with.
A red dash sign-meaning the device is inactive on all the servers that are associated with it.
A crescent for partial meaning the storage device inactive on any of the associated servers.
Actions:
Edit: You may edit parameters of allowed fields in any of the existing Storage record.
Clone: You may clone any existing Storage record to create a new one with few unique parameters.
Delete: You may delete any/all of the existing Storage Device records by selecting multiple records if they haven’t bound with any backup set.
Adding a Storage Device
When you click on Add Storage (Simple Disk, Legacy, Cloud Storage, or Tape Storage), the options for that device are displayed in the right pane, as shown below.
Click on desired storage option and enter the details as shown below and Click Save. Devices already configured are listed in the Storage main page along with buttons that allow you to Edit, Delete, and Clone the device, as shown above in Storage page overview. When there are more items that can be listed on one page, page navigation links at the top of the table allow you to move between pages.
Advanced Options:
Each Device has advanced options that are required to be modified only under special circumstances or when the Zmanda Support team requests you to do so. Please see the specific device section about the advanced options available.
All devices must have a Name; a descriptive Comment is optional. Device-specific options are described in the subsections that follow.
Disk Storage Device
Using hard disk space for a backup provides a number of important benefits:
· The backup window (in other words, the total time to execute backups) can be reduced.
· Files can be conveniently restored directly from the disk, speeding the restore process.
The disk can be a locally attached disk or NAS or SAN device. The disk must accessible from the Amanda server.
Device Name
A unique name for the Device that will be used in the further configuration.
Root Path
The directory where the backup images will be stored, specified when the device was configured in the Storages page.

Root Path
The directory where the backup images will be stored, specified when the device was configured in the Storages page.
Tip: The amount of free space available to hold backup images is an important consideration for fast retrieval of data. To ensure effective restore capabilities, set aside sufficient disk space to hold more than one full Backup Set worth of Data. Just how many full Backup Sets you should keep on disk depends on the data and your sites requirements for quick restores of accidentally deleted data. The more full backup images stored, the longer the retention of accidentally deleted files. Start with enough space to hold three full Backup Set images and adjust this number as experience dictates.
Tip: Because there is no value in creating a backup of a backup on the same media, Zmanda recommends that the drive that holds the vtapes be excluded from the Backup Set that points to the vtapes.
Reserved Percent
Most file systems reserve a certain amount of free space. This value is used for free space calculations to provide ZMC warnings when the backup volume is running out of space.
Advanced Options for Disk should not be modified unless Zmanda Support Team recommends you to do so.
Tape Changer
The user can now detect the changer, tape drive and the Data Transfer Element associated with the tape drive easily. This especially helps in identifying a barcode mismatch if it all it occurs.
Prerequisites:
Mt-st is required to be installed to check the status of the tape drives at the ZMC server.
Identifying the Tape Changer:
The persistent name of the changer is displayed while creating tape storage. Persistent names cannot be changed which enables the user to know which changer is used while creating tape storage itself. While discovering the Tape changer for the first time, a warning message will be displayed whcih will suggest, Not to use the tape changer if it's associated with an active backup.
After creation of the Tape Storage below are details which are visible to the user :
Device Name
A unique name for the Device that will be used in the further configuration.
Tape Changer
This information is provided for information only and cannot be changed. It can be changed in Storages page.
Comments
Enter a descriptive comment, such as the physical location of the device or any operational notes
Bar code Reader
You can disable barcode if the tape does not have barcode labels. This is not recommended because it is difficult to keep track of Amanda media labels and tape. Users will have track this on their own if the barcodes are not enabled.
On Linux servers, the output of lsscsi and mtx output is provided as a guide to fill out the values as shown below. On Solaris servers, mtx command output is provided (lsscsi command is not available on Solaris).
Cloud Storage Devices
ZMC supports most of the cloud platforms that can be used as Storage devices for backing up the data. Below are is the list.
Amazon S3

A unique name for the Device that will be used in the further configuration.
Storage Options
· Standard
· Reduced Redundancy (RRS)
Comments
Enter a descriptive comment, such as operational notes, Google account information.
Cloud Encrypt
User can opt for AES256 encryption of data that’s being backed up.
Bucket Names
Either of DNS or URL Path can be used for Bucket names.
Secure Communications
Enable this to perform secure SSL transfers of data to and from Amazon S3 cloud. Zmanda recommends enabling secure communication.
Google Cloud Platform
Comments

Storage Option:
· Nearline
· Standard
· Durable Reduced Availability
You can use storage that has less availability. This storage is less expensive. This value cannot be changed after it is set. Changing this value does not migrate data in the cloud.
