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 following
example, backup file 1 (Test_2013-02-05_16-00) 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_2013-02-05_16-00 incremental
2. Test_2013-02-06_16-00 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.
