Backups in WPCloudDeploy is a relatively simple process. We only offer one option in the UI – backup to Amazon S3. (But, you can use our command line scripts for many other backup options.)
In order to set up your backups, you will need two things:
Once you have those two things in hand you can configure your backups in WPCloudDeploy.
Backups have an automatic delete option that purges files after a certain number of days. On our settings screen this is called Retention Days.
Retention days can apply to the local versions of backups that we keep on the server or to both the local and remote backups. By default we don’t delete files that have been uploaded to S3.
We suggest you set retention days to somewhere between 3 and 5 and that you do NOT turn on the option to to delete the remote backups. This allows you to quickly restore a recent backup from files on the local disk while storing additional backups for the longer term in S3.
As of version 4.2.5, you can set the retention days to -1. This will cause the backup scripts to never store any backups on the local server disk. For users with lots of small sites on a server, this can help reduce server costs. However, it is not an option we recommend. If you do use it, please make sure that you also have a secondary backup for each of your sites – you can use backup plugins such as UPDRAFT PLUS on each of your sites.
When you look at your backups in your S3 buckets you should see three files for each backup.
These are not proprietary formats. You can download them at any time and decompress them using a tool like WinRar on windows. They can also be decompressed natively on Linux.
Each site you backup to a bucket will be stored in a separate folder. The folder name will be the site’s domain name. With this structure it’s easy to use the same bucket for multiple sites without having to dig around for the backup from a particular site.
You can set up a few different scenarios:
Install a set of default credentials under the settings screen:
Note that this procedure does not actually apply these credentials to your sites and servers. Instead, you need to go to each server (or site ) and configure backups there that will use these credentials.
To enable backups for a site.
Now setup the site backups as follows:
To enable backups for all current and future sites on a server:
You cannot control backup schedules. We schedule backups to run SEQUENTIALLY in order to avoid over-taxing your server with multiple simultaneous backups. So we start the backup job at a specific time and then run through all the sites one at a time.
If you really really want to control the start time of the job you can edit its CRON manually from the command line. But you will not be able to control the start time for an individual site – unless you only have a single site on the server.
Most users just set a retention value and let the servers automatically delete old backups. However, sometimes you just want to lend a helping hand. On both the SITE DETAIL and the SERVER DETAIL screen you have two options.
When it comes to backups, you can never have enough. So, just as with security, we strongly recommend that you have a multi-tier strategy.
If there was ever a single piece of advice you took from us as you read through this documentation, it’s this section, right here! Employ a multi-pronged, multi-layered approach to your backups and you’ll never regret it!
We know from personal experience that restores can fail for any number of reasons. The last thing you want to deal with is the realization that you only have one type of backup and those have been lost or are unusable for some reason. You’ll sleep better at night if you employ a multi-layered backup approach.
We do NOT image your servers – only sites and site-data are backed up. So, if you modify, change or otherwise add stuff to the server, you should definitely enable server level imaging at your cloud provider! Otherwise you will have no backups for the things you have added.
If you’re worried about the costs of backups on S3, we suggest doing the following to keep the costs as low as possible:
Amazon has made creating life cycle rules on buckets very easy on their S3 console.
Deep Glacier fees are $0.00099 per gigabyte. Note: Deep Glacier and Glacier are two different storage types. Glacier charges are 0.004 per gigabyte.
After one year you can start purging your files if you like. But, given the costs it might not be worth the time. At $0.00099 per gigabyte, 10 terabytes of storage costs $10.00 per month.
Deep Glacier is appropriate for files you will not use on a regular basis. It is recommended for files that you will use once every six months or so. Retrieval times for data moved to this storage level is measured in HOURS. So you don’t want to move your recent backups there. But after you have accumulated a few weeks of backups you can probably move your older backups there.
What’s the downside? There are three that should be considered:
One other consideration – there is a tiny portion of Deep Glacier cost that is billed at standard S3 rates – here’s the amazon fine-print about that:
** Amazon S3 Glacier and S3 Glacier Deep Archive require an additional 32KB of data per object for S3 Glacier’s index and metadata charged at the appropriate storage class rate. Amazon S3 requires 8KB per object to store and maintain the user-defined name and metadata for objects archived to S3 Glacier and S3 Glacier Deep Archive. This enables you to get a real-time list of all of your S3 objects using the S3 LIST API or the S3 Inventory report. Objects that are archived to S3 Glacier and S3 Glacier Deep Archive have a minimum 90 days and 180 days of storage, respectively. Objects deleted before 90 days and 180 days incur a pro-rated charge equal to the storage charge for the remaining days. Objects that are deleted, overwritten, or transitioned to a different storage class before the minimum storage duration will incur the normal storage usage charge plus a pro-rated request charge for the remainder of the minimum storage duration. Objects stored longer than the minimum storage duration will not incur a minimum request charge. For each object that is stored in S3 Glacier or S3 Glacier Deep Archive, Amazon S3 adds 40 KB of chargeable overhead for metadata, with 8KB charged at S3 Standard rates and 32 KB charged at S3 Glacier or S3 Deep Archive rates
If you use your S3 account for more than just backups, we strongly suggest that you create a unique set of IAM credentials just for WPCloudDeploy Backups.
For even better security, you can create a different set of IAM credentials for each site. Each credential set should have restricted access to just that site’s bucket or folder. If you do this, you will need to configure backups for each site individually instead of using the option to backup all sites. But it reduces the chances of a bad actor being able to access or corrupt all your backups simultaneously.
You can only use one set of AWS credentials for all sites on a server. BUT, you can use different buckets for different sites if you like – as long as the credentials have authority to access the bucket.
By default, backups will be sent to S3 and stored in their own folders inside the specified bucket – one folder per domain. But, you can specify a folder along with the bucket name if you’d like to group certain sites together – eg: wpbucket/my-dev-sites/.
When taking an on-demand backup of a large site, it might seem as if the backup screen is “stuck”. This is because it is taking a very long time to zip up the files and, while that is happening, there is no output being sent to the console.
If you know that your site is large then you should be patient and let the backup run.
You can always check the COMMAND LOG screen to see if the backup is completed. Sometimes navigating away from the browser tab while the backup is running can cause the JS to pause and not check for the logs. When this happens the backup might be completed but you will never get the notice (you can thank the browsers for trying to optimize JS execution by pausing or slowing down JS that is in a background tab.)
If the backup is completed, you will see a notice in the command logs that say BACKUP HAS BEEN COMPLETED – see image below:
Our backup scripts have some additional options that are not part of our UI/control panel. You can access these if you are willing to use the Linux command line.
When you log into your server as root (or “ubuntu” in the case of AWS servers), you should find a file whose name is 08-backup.sh in your home folder. If for some reason the file is not there, you can upload it as follows:
Now, you can execute the file by running: sudo bash ./08-backup.sh
This should bring up the following screen:
Options 13 – 14 are the advanced options. With these you can remove backups that are old or that remained behind after sites were deleted.
Once credentials are applied to a server, they will continue to be used until you go back to the server or site screens and reapply the backup settings. There are some implications to this.
One of those is that if you change your default credentials in WPCLOUDDEPLY->SETTINGS, they are NOT automatically applied to your servers and sites – even if those servers and sites are supposed to be using the default credentials. Instead, they will continue to use the old defaults until you go back to each server or site screen and re-save the backup settings there. At that point the new defaults will be read and transferred to the server.
