TSM has undergone rapid change in the recent past. Not least is the rebranding of Tivoli Storage Manager (TSM) to Spectrum Protect. This is all part of IBM’s Software Defined Storage strategy, which integrates the range of IBM Storage hardware and software products into a unified Software Defined Storage range
Perhaps the most fundamental change between TSM5 and TSM6 & TSM7/Spectrum Protect is the introduction of DB2 as the Server database. This has significant scaling, reliability and management benefits that allow Spectrum Protect to support the increasingly large and diverse backup environments found today
A conversion process is required to migrate existing TSM5 databases to the newer DB2 format which we can assist with.
New features to Spectrum Protect may persuade those who are still unsure of the benefits of upgrading – especially since most of these features are included in the base licence, which is a compelling argument from a financial perspective in itself.
This blog highlights some of the most significant new features
Spectrum Protect servers support node level replication where node data is replicated between source and target servers.
A Spectrum Protect server can act as both a replication source and replication target.
Crucially, both servers in a replication relationship maintain an inventory of their local and replicated files. This can be of great benefit in Disaster Recovery since it avoids having to restore a Spectrum Protect database, and access tape volumes, at the failover site.
Automated failover is supported, with data being restored from the target server if the source server fails.
Spectrum Protect has introduced two new data compression techniques. When combined, they offer a cost-effective alternative to dedicated deduplication appliances and Virtual Tape Libraries
Both client side and server side deduplication are now available. This can significantly reduce storage requirements and client side deduplication can also reduce backup data transfer.
Inline deduplication was introduced in Spectrum Protect, where data is deduplicated as it is ingested. Out-of-band deduplication, where data is deduplicated after ingestion is also supported.
Spectrum Protect now supports inline server side compression for container storage pools. This can be used in conjunction with inline deduplication to maximise data reduction.
Recently introduced is a new type of storage pool – the container storage pool.
This is an object-based storage pool that can be based on either:
- Directory hosted on local server
- Cloud. Both on premise or public cloud are supported using CleverSafe, IBM SoftLayer or OpenStack Swift
This key feature now allows users to develop cloud and hybrid-cloud based backup solutions – for example with Spectrum Protect replicated data being located in the public cloud for disaster recovery use.
Another major benefit of container storage pools are that since they do not consist of volumes, there is no requirement for volume management techniques such as reclamation and collocation.
Greatly enhanced features to support Virtual Environments, including VMWare and Microsoft Hyper-V.
‘Incremental Forever Forever’ backup strategy which requires only one initial full backup. Afterward, an ongoing (forever) sequence of incremental backups occurs.
Full VM instant restore, where a VM is available instantly while the restore continues in the background
Self-service file restores. This significantly simplifies file restores for users, who can now restore files from a browser interface without any input from the Storage administrator.
