Introduction

Goal of ImageMaster Archive Recovery Management

When storage systems become temporarily unavailable in an ImageMaster 9 archiving solution, ImageMaster Archive Recovery Management (ARM) ensures that archiving can proceed as soon as possible. After such incidents have been resolved, ImageMaster ARM offers to reestablish the archiving redundancy levels previously present in the storage systems.

ImageMaster archiving solutions can opt to use low cost storage which is more likely to experience an irreparable hardware failure during its lifetime. In such cases ImageMaster ARM with the help of backups of such low cost storage provides the possibility to effectively resynchronize storage systems to a consistent state.

This system manual provides a step-by-step guide on how to use ImageMaster ARM to safely handle temporary storage outages.

ARM operations are executed by using the arm-tool, which is a Java based command line tool described in this document. In the web service reference, ARM operations are also grouped under “ImaRecoveryService” [WS IS].
