Was sind P2BU Dateien?

Nach jeder Installation finde ich mehr von Dateien mit Endung P2BU im PP Verzeichnis?
Wozu sind diese gut?

The Native Touchpoint stores a temporary backup of files that are deleted or overwritten during the installation process. If an installation succeeds the backup is simply removed. If however the installation fails, the files in backup are restored to their original location. If the restore works as expected, the backup copy is also removed. Two “disaster” cases remain:

It was not possible to restore files (probably because of faulty hardware, running out of disk, or manual tampering with files during the installation).

The system crashed during the install

The backup is placed in a directory under the directory referenced by the system property “java.io.tmpdir”. The backup directory has a name with the prefix “.p2bu” which is followed by a unique key per running backup instance. Under the “.p2bu…” directory files are stored in a hierarchy that reflects their original location.
