Appendix A: Attachment store types

Attachment store types overview

Archive Manager supports different storage types for storing attachments and compliance messages. Details on using each of the storage types are provided below. The storage types supported by Archive Manager include:

NTFS / Windows File System: This is the default option, and stores files on standard disk.
NetApp SnapLock: SnapLock provides fast WORM (Write Once Read Many) storage on magnetic disk. It uses non-rewritable, non-erasable disk storage protects data until a specified retention date.
EMC Centera: This option uses an external EMC Centera server or cluster to store the attachments.
Caringo CAStor/Dell DX: This option uses a Caringo CAStor storage cluster or Dell DX Object Storage Platform to store attachments.
Bridgehead HDR: This option uses an external Bridgehead HDR server to store attachments.
IBM DR550: This option uses an IBM DR550 running IBM System Storage Archive Manager (SSAM) to store attachments.

Archive Manager allows more than one type of storage to be used on a running system. However, only one storage location can be considered the default storage location at a time.

When installing Archive Manager, you set the attachment store type on the Attachment Store Type screen. Once the product is installed, additional attachment stores can be added. This process is described in the section Common scenarios for editing the configuration.

In all cases, Archive Manager stores each unique attachment as a single file or the equivalent unit. Archive Manager performs no compression or encryption. This is left to the underlying storage system.

Some attachment store types are deprecated in Archive Manager for new installations. Existing customers on deprecated file storage types are fully supported and will continue to be supported until a migration plan is in place and migration tool is available to move to a new storage type.

NTFS/Windows file system

The file system is the default storage mechanism for Archive Manager. This is a directory structure, usually in C:\ArchiveManager\Data, with each file stored represented by its database id and file type. For example: 34.gif

These files are stored in blocks of 1000 files per directory. Each database ID has up to twelve 0’s added to the front. For example, 34 becomes 000 000 000 034, and this is converted in a directory name:

By default, the entire tree, from c:\archivemanager\data down, is set to be compressed using NTFS compression. These files will not be rewritten, so any backup scheme can be used. It is recommended that you do an incremental backup.

NetApp SnapLock

The NetApp SnapLock Setup Wizard allows you to create volumes or WORMS on which Archive Manager can put attachment stores. The volumes containing attachment stores are an effective tool for compliance.

The NetApp SnapLock Wizard is run from the Archive Manager Installer. Run the installer during the installation process, unless you already have all the necessary volumes created.
