In this second and final post comparing Arcserve UDP and Company Vm, we will focus on some very important differences in our respective backup and recovery technology. Let’s first remember that Company Vm focuses only on data protection for virtual environments, and by definition, creates serious gaps in their ability to support hybrid environments.
Support for physical systems is a built-in capability with Arcserve UDP. While many production environments may be highly virtualized, not everyone is 100% virtualized yet, nor do industry analysts seem to believe it will ever be the case. This underscores a very real need to offer support that protects physical systems in addition to virtual servers, or customers have no choice but to run multiple solutions, which is counter-productive and doesn’t deliver coherent restores across the environment. Arcserve UDP supports both physical and virtual sources, and rrestores to physical and virtual destinations.
In terms of flexible recovery options, Bare Metal Recovery (BMR) is a “must-have” in a data protection solution, and allows you to quickly recover when a complete system fails. Customers often resort to “adding on” other BMR products when their “virtual system only” product does not offer this capability. With Arcserve UDP, customers get instant BMR to support local and remote bare metal recovery of Linux physical machines. Instant BMR provides better restore capability and an improved end-user experience by enabling instant access to a target machine prior to the entire recovery process being finished. This feature empowers users to instantly regain access into a failed physical Linux node, and is a first of its kind.
Let’s talk about tape. Tape is not a primary backup medium anymore as most end-users today have adopted disk to disk strategies (i.e. backing up to disk vs. tape). However, there are still many reasons to use tape as a secondary backup medium for long term retention or archival requirements. Company Vm’s V9 technology introduced “advanced” tape support, including parallel processing, concurrent copy sessions and GFS Rotation schemes (Grand Father, Father, Son). However, you can’t “improvise” tape support; it takes years to master it – and Company Vm’s support is very basic. In contrast, Arcserve UDP offers actual advanced tape features, such as: multiplexing (2-32 jobs), multi-streaming, device group and media pool, GFS rotation and synthetic backup, append media, media maximization, media pool manager, tape library option and auto library detection and configuration, bar code support, auto inventory, auto eject media, monitor blank media quantity, tape management and tape vaulting, auto tape cleaning and configurable block size for tape. We could go on, but hopefully you see the stark differences in our tape support.
As far as remote office protection, it’s important to protect business data no matter where your employees are located, and to protect those data nodes in an efficient fashion. Company Vm’s solution requires a separately installed WAN Optimization service (and that’s for their Enterprise edition only). In comparison, Arcserve UDP’s Recovery Point Replication is included in all the versions of our solution, and our Gateway feature provides fast WAN Transfer that makes it highly efficient.
There are also differences in how Arcserve approaches cloud backup and replication, compared to Company Vm. Cloud backup and replication allows for the backup product console to connect to a cloud-based service provider. This lets you replicate VM copies or backup points offsite into the cloud as a disaster recovery solution.
With Arcserve, the target Hypervisor is cross-compatible, and the source and target Hypervisor can differ in this instance. Also, Arcserve supports this on physical servers at the source which allows for physical to virtual (P2V) to the service provider. With company Vm, one of the limitations is if you’re replicating from Hyper-V, your service provider must provide Hyper-V. Not very flexible, is it?
Finally, in contrast to Company Vm’s software and cloud partnership only, Arcserve UDP is available as a software solution but also as an appliance, in addition to the Arcserve Cloud.
