This wasn't an issue with our data rate change test as each incremental copied 1.8GB of new data and the corresponding indexing task took around five minutes. However, for the 44GB backup of the remote server, the subsequent indexing job took an unbelievable 17 hours for an average speed of 2.6GB/hour.
The biggest problem with these indexing tasks is they lock the vault while they are running so you can't access the data held within. This means you can't run further backups to that archive or recover data or volumes from it when an indexing job is running.
We discussed this at length with Acronis and it suggested placing the vault on one hard disk and the index database on another. We tried this on the test server but found performance of the indexing task for the remote server backup didn't improve at all.
File, folder and volume recovery tasks for specific systems can be run swiftly from the main management console.
There's no denying Backup & Recovery 10 delivers an impressive range of backup, restore and disaster recovery features along with good centralised management. However, if it's deduplication you're after we suggest checking out ARCserve r12.5 as CA includes it as standard and it's a lot more efficient with large amounts of backup data.
Verdict
Acronis is one of the best disk imaging products around and this latest version offers a fine selection of server data backup and recovery tools all easily accessible from a central management console. However, we were not impressed with the optional data deduplication feature. Although it returned good storage saving ratios, the extremely poor indexing performance makes it highly unsuited to large businesses whose data changes at a rapid rate.
