Arcserve UDP vs. Company Vm – Part 2

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 introducedadvanced” 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.

Arcserve UDP vs. Company Vm. – Part 1

We recently introduced the new release of our award-winning Arcserve UDP software, so we think it’s the perfect time to provide a high level comparison between it and Company Vm’s recent V9 release.

Starting with one of the biggest differentiators is choice – we give our customers choice in how to consume Arcserve technology with a variety of integrated offerings, including software, appliances and a DRaaS cloud. We also offer the option of a High Availability (HA) module within Arcserve UDP, which means zero or very close to zero data loss (Recovery point objective =0), and with failover, virtually no time needed for recovery (Recovery Time Objective =0).

In contrast, Company Vm only offers software and cloud partnerships. It doesn’t support physical servers, nor does it offer appliances. Also, the company positions itself as providing “always on” capabilities, however it seems that their definition of availability means getting data back in 15 minutes. We hate to point out the obvious, but this isn’t High Availability, and it certainly isn’t “always on.”

In terms of eliminating redundant data through deduplication, here are the facts:


  • Arcserve UDP incorporates true, source-side global deduplication, where the deduplication domain is at the backup server (RPS) storage level.
  • Using Arcserve UDP, all physical and virtual sources will be included in the same deduplication domain, including physical Linux nodes.
  • Real life customer results have been astounding, showing a reduction in storage of 500 TBs to less than 13.4 TBs on a backup disk (that’s a 97.3% decrease)! This means a smaller storage footprint and much lower costs.

Company Vm

  • Company Vm’s deduplication is across a single backup job; hence they recommend an “add-on” Purpose-Built Backup Appliance. Can you hear this noise? Yes, it’s your budget being siphoned off…
  • Company Vm is focused on third-party storage vendors (HP and Data Domain) to assist in reducing backup storage. Makes sense, if your technology can’t do it, have the hardware guys do it. It’s your money, remember…

In the case of Instant Virtual Machines, we offer more capabilities and recently won three best virtualization solution awards at VMworld – an interesting fact given that Company Vm focuses almost exclusively on virtual environments (whereby we specialize in recovery of all environments). Nevertheless, here a few facts:

  • Company Vm offers Instant VM capability. Arcserve offers Virtual Standby Machines and now Instant VM and Instant Bare Metal Restore.
  • We introduced Instant VM in the latest release of Arcserve UDP. Like Company Vm’s v9 release, Arcserve UDP offers vPower Cache functionality, however Arcserve UDP can also support instant VM restore across hypervisors.
  • Unlike Company Vm, Arcserve UDP can instantly restore a VMware VM onto Hyper-V, and vice versa, while also protecting physical machines and enabling instant VM recovery of a physical node (P2V). It’s evident that instant VM in Arcserve UDP offers more bang for its buck.

We mentioned awards, here’s more detail: Arcserve UDP won three Best of VMworld awards last year. The first was for the Best BC/DR Solution for Virtualized Environments in San Francisco, followed by the Best BC/DR Project and Best of Show in Barcelona. We’re very proud of our achievements, but the best reward is to see our happy customers and the increasing number of businesses switching from the other company’s solution to Arcserve UDP.
