备份服务进入测试阶段

更新:Linode的备份服务已经推出!

我很高兴地宣布,我们已经启动了新服务的测试计划:Backups您可以在这里了解有关测试计划进展的更多信息:

Linode备份服务

我们希望你有备份。见鬼,我也想有备份。但它们的配置和监控是很繁琐的。我们都听说过这样的故事(也可能经历过),当你需要一个备份时,在配置它们很长时间后,你发现它们已经几个月没有成功运行了。因此,我们对Linode备份服务的目标是雄心勃勃的:创建一个可靠的、冗余的和高度可用的系统,它易于使用(设置后就可以忘记),价格合理,并且可以正常工作。

描述
Linode备份系统是为您的Linode设计的一个易于使用、可靠和冗余的现场备份解决方案。它在执行备份时不会对您的运行系统造成任何干扰,并无缝地集成到Linode管理器中。

备份
有四个备份槽:其中三个槽是自动执行和轮换的:一个每日备份,一个2-7天的备份和一个8-14天的备份。第四个备份槽是一个用户发起的快照,在另一个用户发起的快照之前一直保持原位。

你可以从一个2小时的窗口列表中配置启动自动备份的时间--你希望在这个窗口之前执行任何数据库转储。你还可以配置一周中的哪一天来进行周报。

还原
你可以将备份恢复到你账户上的任何一个Linodes,即使它没有启用备份功能。目前只有完全恢复是可能的。

冗余度
我们建立了一个定制的分布式和可扩展的存储引擎,它将在至少两个存储节点上复制你的文件。甚至你的备份也有备份!

特点和限制
备份系统必须能够在主机上装载你的磁盘镜像。如果你在你的镜像上使用fdisk来创建分区,或创建加密卷,或除了使用我们的部署或磁盘镜像创建工具外,做任何其他事情,我们将无法备份数据。备份系统在文件上操作,而不是在块级上操作。

一个失败的备份永远不会轮换出一个好的备份。如果一个备份在每周备份的当天发生故障,那么下一个最古老的备份将被用于该周的时段。

在随后的增量备份中,那些已经被修改但长度相同且没有任何元数据变化(如mtime)的文件将不被视为 "已修改"。

目前,只有ext2/3卷可以被备份。 这一限制将在即将发布的版本中被删除。

ACL被正确地备份和恢复了。

价格结构(暂定)
Linode 360:5.00美元/月
Linode 540:7.50美元/月
Linode 720:10.00美元/月
Linode 1080:15.00美元/月
Linode 1440:20.00美元/月
Linode 2880:40.00美元/月

备份服务测试版

我如何参加备份服务测试版?
参与测试版是免费的。

我们只在新泽西州纽瓦克的设施中部署了存储硬件。因此,目前,你必须在纽瓦克有一个Linode才能参加备份服务测试。在该Linode下打开一个票据,要求我们启用备份。

测试结束后会发生什么?
备份服务将被安排为自动关闭。然而,我们会给每个人保留备份服务的机会,并开始收费。

有什么样的风险?这东西能不能用?
对你现有的数据没有什么风险。然而,我还不会依赖我们的备份服务作为你唯一的备份形式。在测试期间,备份可能不一致或不完整,或者我们可能需要擦除所有的备份数据并重新开始。换句话说,保持你自己的备份,不要依赖这个东西工作。我们已经警告过你了!

其他设施的情况如何?
亚特兰大和达拉斯在本月晚些时候,弗里蒙特在5月初。

想了解更多吗? 请在备份测试论坛中关注。

    Sounds good but it’s slight overkill for me (and some others based on the IRC talk about snapshots).

    I know you’re going for the simplest option for users but it would be nice if, in time, you could offer some off-machine, non-RAID, cheap storage so I could do a daily dump of /etc, /home, etc. About 1 gig for me — a lot less HD space than storing 4 18gig snapshots

    I know I can use s3 (et al) for this but it would be a nice extra if there were something I could just tuck into my fstab and cron up a copy command.

    One thing that would be nice is if the backups were priced by data usage rather than by Linode size. We only have a larger node now for RAM / CPU rather than for space.

  3. Author Photo

    I second both Oli and Scott and would like to add that options to only include certain directories to reduce size and keep the backup focused on important stuff only.

    I was looking for backup.. Today I signed up before seeing this blog.. I was worried..Now thanks a lot.

    may be, you can reduce price of the lower end packages, which will add cost advantages..

  5. Author Photo

    Nice to know!

  6. Author Photo

    I second Fred, Oli, Scott and also would like to have cheap off-machine non-RAID storage for non-backup purposes.

    I’d agree that the bells and whistles requested above would be nice…but zowie, I’ll be adding the service as-is to my 360 account for $5/month in a second! $60/year for that level of backups way, way way more than pays for itself in peace of mind. Count me in! Great job.

    Thats a bit over priced for a simple small backup needed, I’ll stick to as3

  9. Author Photo

    I don’t see this as being overpriced at all, I expect to maintain my offsite backup jobs I’ve setup…. but I’ll be signing up for this as well.

    I guess it just depends on how much money your data is worth to you. For those of us running a company website, and in my case $10/month, is totally worth it, without question.

  10. Author Photo

    How about an ala carte service? Maybe we could set up a schedule and get charged per backup? $2-5 per month per backup?

  11. Author Photo

    i think backup costs are fair. i’m looking forward to use it when it comes avaiable.

  12. Author Photo

    Personally, because I am obsessed with improbable disaster, I would like to request being able to have backups at different Linode data centers. I know this introduces a lot of bandwidth use, but if you sold backup for a Linode360 at $5 per data center and just use the bandwidth against our allotment — well that’d be the cheapest geographically distributed backup solution out there. I know this is overkill for many, but the few of us that are obsessed, well we’d love it.

    PS. I know I can mimic this by having Linodes everywhere, but that’s a waste of money imo because I don’t mind hosting from just one place, I just want my backups spread out.

    It noted Fremont in May, but no further updates. What is the status of this offering, is the beta available in Fremont, and when do you expect it to be provided as a paid for service?

    Backups are now available in Newark, Dallas, and Atlanta. Submit a ticket if you wish to participate.

    Codeminding is waiting for linode backup plans.

    any updates on the backup service as well as the pricing? *raising hand* on a per GB pricing instead of fixed rate/size per server instance type.

    “any updates on the backup service as well as the pricing? *raising hand* on a per GB pricing instead of fixed rate/size per server instance type.”
    I second that, based on image size is better. My 2880 Linode only uses a 20GB disk image of the 160 GB available.

    Would love to hear any updates on this… I’m holding out from switching to Linode from Slicehost until this is available!

  19. Author Photo

    Echoing just about everyone above, it would be wonderful to have some sort of an update on backups.

  20. Author Photo

    Another upvote on a status update please!

    Currently looking at provisioning a VPS for a client. If you can tell me your backups service has recently gone out of beta because it’s going live _very_ soon (and not because you’ve abandoned it!) you will get the business. If not, I’m afraid it probably will go to Slicehost.

    Count me as one more that would *love* a status update on this.
