Backup Sets
- The Backup Set is a key concept that simplifies and optimizes the enterprise-wide backup system.
- A Backup Set is a collection of configuration and backup polices.
- It describes what to backup, how to backup, where to backup to and when to backup.
- All ZMC backup, reporting, monitoring and recovery actions are performed in the context of the Backup Set.
- Backup Sets cannot share media volumes.
- For example: Two Backup Sets can use the same tape changer (simultaneously) but each should have a separate set of slots that can be used.
What Backup Set Contains
- A Backup Set consists of:
- a unique name identifying a list of hosts, directories, excluded files, etc.
- that are backed up to a tape or disk via holding disk or otherwise
- whose full and incremental backup schedules are automatically configured by Amanda
- and which employ a common set of parameter/algorithms for backup.
- ZMC enforces that two Backup Sets do not write to the same tape or to the same directory in case disk is used as the backup media.
- ZMC also enforces that it does not accidentally overwrite a tape/disk belonging to another Backup Set.
What Backup Set Does
- A Backup Set allows a user to optimize the processes of Backup and Restore.
- Each set of data that need to be backed up in a similar way, could have its own Backup Set.
Multiple Backup Sets
- ZMC permits and encourages the use of multiple Backup Set for the enterprise.
- For many enterprises, one Backup Set may suffice.
But
- when there is large diversity in data,
- or when there is a need to backup certain data on tape and others on disk,
- or some via a holding disk and others without it,
- or different algorithms to work on different data are required
- or a user wants to experiment with different options and see what suits best
multiple Backup Sets can be deployed.
Create /Open a Backup Set
- The Begin Button on the Welcome page brings a user to the Create/Open a Backup Set page.
- The left panel (No 1 above) allows a user to create a new Backup Set.
- This can be done with the help of a Template or without one.
- Templates
- ZMC has a number of templates to help a user to create a Backup Set.
- To create a new Backup Set from scratch, click the drop down box and select <No Template>
- To create a new Backup Set from a template choose any of the other options in the drop down box. The templates currently available are:
- harddisk
- single-tape
- tape-changer
- Backup Set Name
- Choose a unique meaningful name for the Backup Set.
- Comments
- Comments play no active role in the backup process.
- They are intended to be a short reminder for the user.
- Most sysadmins enter the key parameters of the tape system here. This field can be left blank if the user does not want to add any comment.
- Templates
- The right panel (No 2 above) allows for the opening of an existing Backup Set.
- Choose this option to Edit/ Monitor/ Report/ Restore Backup Sets.
- Once a Backup Set is configured and activated after verification, the backups happen automatically.
- ZMC is not needed to perform the backups.
- The 'Backup Set Name' drop down box shows the list of all existing Backup Sets to choose from.
- Once an existing Backup Set has been selected, its comments will also be displayed.
Go Button
- Click the Go Button to enable the tabs for various functionalities.
