available, but you must know which media to use and what needs to be restored, for example, the exact file name.

The IDB also keeps information on how long the actual data on the media will not be overwritten.

Data protection, catalog protection and logging level policies influence the availability of data and access time to data during restore.

Enabling the browsing of files and quick restore

To restore files quickly, both information about backed up data in the catalog and protected data on the media, must exist. Information in the catalog allows you to browse, select, and start the restore of files using the Data Protector user interface and allows Data Protector to quickly locate data on backup media.

Enabling the restore of files, but not browsing

Once catalog protection has expired and data protection is still valid, you cannot browse files in the Data Protector user interface, but you can still restore data if you know the file name and the media. The restore is slower as Data Protector does not know where on the media the desired data is located. You can also import the media back into the IDB, thus re-establishing the information about backed up data in the catalog, and then start restoring.

Overwriting backed up files with new data

Once data protection has expired, data on the media is overwritten in one of the subsequent backups. Before this happens, you can still restore the data from the media.

TIP:

Set data protection to the amount of time that you must keep the data, for example, one year.

Set the catalog protection to the amount of time you want to be able to browse, select, and restore files quickly using the Data Protector user interface.
