Backup restore chain

0. Test_2013-02-04_16-39 full

1. Test_2013-02-04_16-42 incremental

2. Test_2013-02-04_16-44 incremental

The InterplayRestore tool gives you an option of selecting a partial restore. If you type “y,” you

are asked to select which file in the restore chain from which to start the restore. In the example,

backup file 1 (Test_2013-02-04_16-42) is selected.

Is this a partial restore (y/n): y

Choose an entry in the restore chain to start from ( 1 - 2 ): 1

You are then asked to select how many entries forward you want to restore:

Choose how many entries to restore ( 1 - 2 ): 2

In the example, starting with file 1 and selecting two entries mean that the partial restore will be

run from the following files:

1. Test_2013-02-04_16-42 incremental

2. Test_2013-02-04_16-44 incremental

Results of a Partial Restore

If you perform a full backup, the Interplay Engine renames the original _Database and

_PropertyStore folders before the restore procedure, and creates new folders for restored files

during the restore procedure. The resulting files are similar to the following:

_Database

_Database.1

…

_PropertyStore

_PropertyStore.1

where _Database_and PropertyStore are newly restored from backup files, and _Database.1 and

_PropertyStore.1 are renamed original files.

If you perform a partial restore, the Interplay Engine does not rename the original folders.

Instead, it overwrites database files in the _Database folder with latest versions from the restore

chain and merges streamed property files to the existing _PropertyStore folder.

Displaying a Restore Chain

You have the option of displaying the restore chain for a selected backup without performing the

restore. To display the restore chain, use the /printchain option in a interactive or non-interactive

command line, as shown in the following examples:
