But many things have also changed, with the latest beingthe advent of the cloud. This brings the possibility of the cloudas a backup target but also the need to backup applicationsthat run in the cloud. In this e-guide we look at backupfundamentals like choosing incremental or differential backupas well as using snapshots to replace traditional backup. Wealso provide an overview of strategic considerations for backupin the age of the cloud as well as surveys of the key backupproducts for SMEs and enterprise deployment.Antony Adshead, storage editor

In this bracket we can include CommVaultand IBM.

Applications are placed intodifferent resiliency groups and given priority for restore should an outage occur.Automated simulations take the place of backup/disaster recovery testing, fromvirtual machine to datacentre level, and there is integration with vSphereapplication programming interfaces (APIs) for I/O filtering (VAIO).NetBackup’s CloudMobility targets organisations that want to work in multipleclouds and move data into, out of and between clouds and on-premiselocations. It aims to make these operations automated and offers the ability totest migrations before carrying them out in anger to see if data anddependencies will come out as expected.By contrast, Veritas’s midrange-oriented Backup Exec product seems lesswidely integrated with cloud operations than Netbackup. It is true, however, thatthe big three’s public clouds can be a backup target while disaster recovery canbe orchestrated from the cloud in a link-up with Microsoft’s Azure Site Recovery.So, what’s available via the big three cloud providers’ market places?NetBackup is available in Microsoft Azure and the IBM cloud, AWS offersResiliency Platform and Backup Exec, and Google Cloud Platform offers CloudPoint.

Curtis Preston, guest contributorSnapshot-based backup systems can literally change the game for anyoneinterested in using them as their primary method for backing up and restoringcritical data. Snapshots offer significantly easier and faster backups than anytraditional backup system can provide, and they offer recovery time objectives(RTOs) and recovery point objectives (RPOs) that are also impossible with atraditional backup system. In this context, a traditional data backup system isone that backs up files by placing them into some kind of backup format (e.g.,Symantec Corp. NetBackup image, EMC Corp. NetWorker saveset, IBM Corp.TSM aggregate), and then places that format on tape or disk. However, not allsnapshot backup systems are alike, and not all of them have what it takes tocompletely replace a backup system. In the following, we'll help you understandthe benefits and drawbacks of such a system and allow you to make your owndecisions as to whether or not you might want to investigate using a snapshotbackup system for your organization.When discussing snapshot-based backup systems, there are a number ofmisconceptions that must be dealt with before beginning the conversation. Thefirst of these misconceptions is that snapshots aren't backups at all -- they are

There are those that believe that if a copy of data doesn'tchange form -- such as being put inside a tar image -- then it's not a backup. It'sunclear where this idea came from, but changing form is not a requirement forsomething to be a backup.How are snapshot backups defined?The Storage Networking Industry Association (SNIA) defines a backup as "Acollection of data stored on (usually removable) non-volatile storage media forpurposes of recovery in case the original copy of data is lost or becomesinaccessible; also called a backup copy. To be useful for recovery, a backupmust be made by copying the source data image when it is in a consistentstate." The only part of this definition that snapshot-based backups might havetrouble with is the "usually removable" part, but this is simply SNIA stating theobvious that most backups are placed on tape.SNIA's definition does bring up one very important aspect of snapshot-basedbackup systems -- a snapshot is not really a backup until it has been replicatedto another storage system. This is because a snapshot is a virtual copy of thedata, not an actual copy of the data. If something happens to the volume uponwhich a snapshot resides, the snapshot of the volume will be of no use -- unlessit was copied to another volume via replication.In a traditional backup system, backup software and tapes create the ability torestore multiple points in time. This is a critical function of a backup system, asPage 9 of 34
