"Best backup system for WP. More importantly, the easiest restore system too!"
"Snapshot is a great plugin for Multisite admins to create snapshots of their entire database and all sites."
"Snapshot pro is the flyest WP backup utility on the planet. Snapshot makes migration to and from Multisite a breeze. Thank you very much for the wizardry."
"Security, plugins, themes, advice, support, community, education, performance, and now backups! You can't go wrong."
"Again WPMUDEV proves how much they value their members! Thank you for the generous 10 GB of free storage and what appears to be, a very elegant managed backup solution."
"It’s amazing to see a company that keeps improving things in a way we can focus more on our clients and less on daily tasks."
Have you ever made a change that broke your site, or been hacked and wished you could go back in time?
Snapshot creates full site automated and on-demand backups to both local and cloud servers.
Schedule automated backups or run Snapshot before you change a line of code, update WordPress core or activate a plugin.
Restore points make it easy to try something new and jump back in a flash if it doesn’t work.
Hosted & Convenient
Local backups are fast and convenient for quickly undoing a change, but what if your server goes down or is hacked?
Your active WPMU DEV membership lets you beta test our new secure hosted backups with 10GB of storage and one-click restore from The Hub!
Direct to the Cloud
Redundant snapshots give your site a new kind of security. Backup to your local server, the WPMU DEV Hub and your favorite cloud services.
Destinations make it easy to save directly to Dropbox, Amazon S3, and Google Drive or by FTP and SFTP.
Backup your entire site or use the file selector to choose specific files and save space.
Store as many Snapshots as you like or use rolling backups to remove the oldest backup when a new snapshot is created.
Browse and restore snapshots from the WordPress dashboard, the WPMU DEV Hub or even manually restore from a ZIP backup.
Label snapshots so you can quickly find a specific backup point when you need it most.
He’s Got Your Back
Your WordPress site is valuable, often the accumulation of hours of work. Even well-maintained sites crash from hosting hiccups or faulty plugins.
Protect your site’s future with Snapshot and never get caught with your site’s backend exposed again!
Start by reading Installing plugins section in our comprehensive WordPress and WordPress Multisite Manual if you are new to WordPress.
Once installed and activated, a new menu item will appear in your admin area.
- When Network Activated on a WordPress Multisite, go to Network Admin > Snapshots > Settings.
- When activated on a single site install of WordPress, go to Snapshots > Settings.
Configuring the Settings
We need to first configure the folder where we want these backups done. Click on Settings now.
You can customize the name of the folder here, and change it to anything you like. We’ll move the files already backed up over for you. How cool is that!!
We will then want to set how many records are backed up per request. This is titled Database Segment Size.
The Segment Size can be defined as the number of rows to backup per table per request. The Segment Size controls the backup processing when you create a new snapshot.
During the backup process, Snapshot will make a request to the server to backup each table. You can see this in the progress meters when you create a new snapshot.
In most situations this backup process will attempt to backup the table in one step. But on some server configurations the timeout is set very low or the table size is very large and prevents the backup process from finishing.
To control this, the Snapshot backup process will breakup the requests into smaller ‘chunks of work’ requested to the server.
For example, let’s say you have a table with 80,000 records. This would take more than the normal 3 minutes or less most servers allow for processing a single request. By setting the segment size to 1000, the Snapshot process will break up the table into 80 small parts. These 1000 records per request should complete within the allowed server timeout period.
The next section, Server Info, displays everything you need to know about the particular configuration of your install. This can be very useful information indeed if you ever need to contact support with any issues.
We can then set a new memory limit. Keep in mind if your database is growing in size, then you will need more PHP memory to process that. If there isn’t enough, then PHP will time out with memory errors.
The next settings area allows you to specify files or directories that will be excluded automatically from all snapshot configurations.
You can also setup exclusions specific to a single snapshot via the configuration screen (see Starting A Snapshot below). The exclude logic uses pattern matching. So instead of entering the complete server pathname for a file or directory you can use simply use the filename of parent directory.
For example to exclude the theme twentyten you could enter this one of many ways: twentyten, themes/twentyten /wp-content/themes/twentyten, /var/www/wp-content/themes/twentyten. Regular Expression are not allowed at this time.
The Error Reporting section controls how Snapshot will handle an error condition during the backup / restore processing.
There are two columns for each type of error. The ‘stop’ column controls if Snapshot will abort the current process should that type of error be reached. The ‘log’ column controls if the type of error and details will be written to the processing log. In most cases you want to set ‘stop’ for Errors only. And set ‘log’ for all.
The final section lets you select which zip compression library to use.
The zip library is used during the backup and restore processing by Snapshot.
In most cases ZipArchive is built into PHP and generally faster than PclZIP. ZipArchive uses files whereas PclZIP uses memory for temporary storage when compressing large files.
That’s it for the settings — all done.
*BETA* WPMU DEV Hosted Backups
As of the most recent release, Snapshot can now integrate with our new backup service, which will allow you to store up to 10GB of backups in our cloud. It’s very important to note that this feature is still considered to be in beta, so expect a few bugs and quirks early on. Please report any issues you find in our support forums.
Using the hosted backup system is very simple. You’ll be up and running in a few clicks. You will need to have the WPMU DEV dashboard installed, and be an active subscriber in order to use the Snapshot hosted backup service.
Start by clicking the Full Backups item in Snapshot’s admin menu tab. This will bring you to the settings page. There are only three areas to be concerned with. In the left panel, you’ll see general information about your Snapshot schedule, and a list of all your current backup files, once you’ve created some backups.
In the right panel, you’ll see a box for creating a backup schedule, and one for settings.
In the settings box, you’ll need to enter your Snapshot secret key. There’s a link that will take you to the Hub on WPMU DEV, and you’ll be shown a pop up with your Snapshot key ready to copy. You can also access this by going to the My Websites tab in your Hub, then choosing the site you’d like to add Snapshot backups to, then selecting the Backups tab.
In the schedule box, choose between daily and weekly backups, and set a time when you’d like the backup process to start.
You can select the number of backups you’d like to store remotely in our cloud, and also choose to enable logging, a feature we’ve carried over from the other destinations in Snapshot.
Once you’ve successfully created your first Snapshot backup and it’s been successfully uploaded to our cloud, you may restore it at any time, from either the Snapshot archive on your site, or from the My Websites tab in the hub.
Easy as falling off a log.
Destinations are external locations where you can store your Snapshots so they’re secure and accessible even if your server crashes.
A destination is a remote system like Amazon S3, Dropbox, SFTP or GreenQloud. Simply select the destination type, then fill in the details. When you add or edit a Snapshot you will be able to assign it a destination.
When the snapshot backup runs, the archive file will also be sent to your selected destination.
To set up a destination, simply click the Add New button next to your preferred service, and follow the directions. Go ahead and set up a destination now for the next steps.
Note for Google Drive destinations: when setting up your destination at Google Drive, you may want to double-check under APIs & Auth > Consent Screen that Email Address & Product Name are filled in, otherwise you may get an error.
Note for Amazon S3 destinations: when setting up your destination at Amazon S3, you must set “Amazon S3 Full Access” permissions in the user policy of the user you are connecting with.
Starting A Snapshot
In the Snapshot menu, click on “Add New.”
Here we will want to give our Snapshot a name. It doesn’t really matter what you call it because it’s all relative to you. You can add some notes, as well as a reminder of what you’re performing with Snapshot.
In the next section, you can select which files to include or exclude from the Snapshot.
You can choose to not include any files, include only common files, or select specific files you want to include.
You can also list additional files to exclude from this snapshot. This is handy to exclude very large files like videos that are 2G in size that you may be hosting, but know you have a backup elsewhere.
Next we will want to decide what tables to take a Snapshot of. You have 3 basic options:
- Do not include database tables in this Snapshot.
- Include all blog database tables in this archive. This will automatically include new tables.
- Include selected database tables in this Snapshot.
Selecting the 3rd option will expand the section so you can select exactly which tables you want to include. The first set of options are for the default WordPress core tables — the ones for users, usermeta, and so on.
The next set of options are for the extra tables added by themes and plugins. Any tables added by WordPress, themes, or plugins are all optional, and you can choose which ones you need!
Now we need to tell the plugin when to run & archive the backup.
When selecting the Backup Interval, please note that the Snapshot scheduling process uses the WordPress Cron (WPCron) system. It should be understood that WPCron is not precise. If you schedule a Snapshot for a specific minute of the hour, WPCron may not execute at exactly that time. WPCron relies on regular front-end traffic to your website to kickoff the processing.
You can also specify the total number of local archives to keep for this snapshot. Once the archive limit is reached, older locally stored archives will be removed.
In common cases you may want to set the backup interval to once a week. Then set the number of archives to keep to 52 which would give you a year or backups. But keep in mind on a large site this will be a lot of extra disk space required.
Finally, select where you want to store your backup.
In the Backup Destination dropdown, you can select to archive your backup locally, or choose any of the Destinations you have already set up. If you need another, simply click Add More Destinations.
You can also use the optional Directory to override or supplement the selected destination directory value.
Once you are happy with all your choices here, then all that’s left to do is to click on the “Create Snapshot” button. … So let’s do it!
You’ll then see a new screen that shows you the backup progress as it’s working.
If you need to abort the backup at any time and start over again later, simply click the Abort button that appears next to each segment as it is being backed up.
And don’t be alarmed if this takes a while or if the backup does not appear instantly. These things take time you know. ;-)
Go grab yourself a beverage whilst you wait if you wish. :-)
Once it’s done, the plugin will let you know with a friendly notice:
Where Are My Snapshots? Can I Restore Them?
You will notice in the Snapshot menu there is an option for “All Snapshots.” Click on that, and you will get a list of all the Snapshots you have already archived. It really is that easy!
As you’ll notice on the page, you can edit, run, restore or delete a backup.
You can even view which core & optional tables you backed up by clicking the corresponding link:
At the far right of each snapshot listed, you’ll find links to download the snapshot to your computer or view the archive for that particular snapshot. You can also view or download the log of all actions performed during the backup.
How awesome is all that!!
Importing a Snapshot
If you have Snapshots stored on a remote server, or have manually uploaded them to to your local folder, you must import them first so the plugin will recognize and show the archive in the All Snapshots listing.
Note that if you are importing from a remote server, the remote archive must by publicly accessible as this import process does not yet support authentication.
Once you have successfully imported your remote archive or scanned your local folder, you’ll see a success message with the import results.
If you have set up the archive to save to an alternate directory, then enter the full server path to the directory where the archive resides in the URL field.
You can now select your imported archive, or perform operations on it, from the All Snapshots page.

See you there!
