Quantum在exagrid中选择了乳制品合作普通环境

Faced with skyrocketing data growth and malware threats, a leading French dairy cooperative carried out a proof-of-concept test to choose the best deduplication appliance for their Veeam software. The results were clear—Quantum’s DXi® deduplication and replication was more than 15 times more effective than the competition, providing the right solution for all of the company’s offices.

MaîtresLaitiersdu Cotentin（MLC）是一家卓越的法国乳制品合作社，拥有820家当地农场。每年，它收集和处理超过4亿升牛奶，并将新鲜牛奶，奶油弗拉里切，黄油和奶酪分发到法国，欧盟，最近，在中国新的工厂在Méautis的新工厂中分发。

MLC relies on robust data management and IT services to keep track of inventory, monitor production and manage all of its complex business operations, including payroll, HR and the service activities of the subsidiaries for distribution. “In some ways, Maîtres Laitiers du Cotentin today is just as much a data processing company as a dairy operation—the two parts of the business are fully intertwined and interdependent,” explains Emmanuel Moncuit, the company’s System and Network Administrator.

依赖虚拟化服务器意味着调整数据保护

自2010年以来，大约98％的公司120多台服务器已经虚拟化，这是一个具有亚搏官网app登录入口重大影响的备份和数据保护的策略。这意味着大多数备份职责由Veeam软件执行，直接将数据写入磁盘卷，只有由公司的遗留备份应用程序仍然保护的几个物理服务器。亚搏官网app登录入口

最初，该战略效果;但随着每年大约25％的数据量膨胀，系统开始落后。“我们有很多数据，我们开始缩短我们的备份保留时间，并提供二级站点，博士保护极为困难，因为我们有太多的数据来复制我们的网络，”森泰记得。

勒索沃特危险有助于推动升级

On top of those problems, the team members started to see ransomware attacks against their business. Their backups protected them, but they decided it was time to upgrade their system. “We wanted to be able to create a full backup whenever we wanted in order to have high confidence that we could recover cleanly and quickly, something that the ransomware attacks had forced us to do,” Moncuit explains. “So, we decided to stay with Veeam.”

验证测试用于选择最佳重复数据删除硬件

The question of backup hardware was more complex, however. The team decided that the best approach was likely to be deduplication appliances. “We determined that using deduplication should let us store more data on less disk so we could have a longer retention period, and we wanted it to allow us to replicate backup sets between data centers,” Moncuit explains.

该团队仅发现了两个由Veeam认证的重复数据删除设备，以获得该集成程度：Exagrid和量子DXI。“我们听到了许多关于每个人会做什么的索赔，但决定我们发现系统如何真正与我们的数据和网络有关的途径是建立对硬件的真实测试。

Testing Systems with Different Deduplication Approaches

该项目比较了两种不同的方法来重复使用Veeam软件发送的数据。exagrid使用后处理重复数据删除，其中数据首先直接写入磁盘并以其原始大小保留。DXI设备使用在线方法。它们在备份期间实时删除数据，从飞行中消除重复块，并且仅存储在磁盘上设置的减少的数据。

这两个设备还使用不同的方法来重复数据删除数据。Exagrid Systems将存储的备份文件划分为公司调用“区域”的内容，然后在新文件和旧文件中的区域之间进行字节级别比亚搏官网app登录入口较。DXI Systems在活动备份中查看块，将已使用动态可变块大小与已存储的备份文件中的块进行比较，以最大化数据减少。

相同的数据集急剧不同的结果

Each test included two units which processed the same succession of backup and replication events. The Exagrid used a 42-TB unit in one section of one data center, and a second 20-TB unit in a different area, connected over the company LAN to test replication. The DXi system set up one 11-TB physical appliance in the first data center and, to test replication, installed a virtual appliance in a second, remote data center, connected to the first by a WAN. “We really wanted to be sure that we did everything we could to have both systems following all of the recommended best practices,” Moncuit says.

类似的备份和恢复速度，显着不同的重复数据删除

测试显示了几个优点，使DXI系统成为明确的赢家。“较大的exagrid单位以本机模式存储一个整个备份，以使读取和写入更快，所以我们惊讶地看到更小的DXIS的性能同样好，”蒙卡特说。

但DXI重复数据删除结果更有效，提供了引人注目的好处，包括所需单位的大小和复制效果。“对于我们的远程站点，DXI根本不需要物理设备 - 我们刚刚使用本地VMware环境并构建了虚拟设备，”Moncuit解释说明。

重复数据删除，DXIS提供比Exagrid或备份软件对主要备份作业的重复数据删除超过300％的效果超过300％。由于DXI系统利用其全球重复数据删除，因此在复制时大大放大了这种优势。“在我们的测试中，备份完成后，DXI复制只是几分钟后完成了，因此我们的风险时期 - 完成备份时的差距，并且副本安全地关闭现场 - 非常短，”Moncuit添加。

有效的十倍以上，无需实物设备

When both units replicated new data from a 224-GB backup at one location to an appliance at the other, the Exagrid system sent 21.7 GB of data—a 10:1 reduction—while the DXi’s virtual appliance sent only 1.4 GB—a 159:1 deduplication rate. “The difference between the units—more than order of magnitude—was amazing to us, and it made our decision in favor of the DXi system an easy one,” Moncuit explains.

生产环境结果甚至比测试更好

基于测试，团队在生产环境中安装了DXI单位，很高兴发现真实环境的结果甚至比他们所希望的更好。“在我们的审判中，DXI与Exagrid单位一样迅速，更小，并给予了我们多重重复数据删除结果的十倍，”蒙卡特说，“但生产结果甚至比测试更好。

“由于DXI设备和Veeam软件的组合，我们在更短的时间内备份​​更多数据，对我们现有的WAN复制备份，能够快速恢复文件，并具有保护我们从赎金软件攻击中的数据的保护。”
