  6. 6. © 2017 Rick Radko, r3df.com More reasons you need a backup Hacking/ Malware/ Virus:  Can completely trash a site.  May have all your files deleted.  Every single file could be altered.  There are over 1000 files in an empty WordPress install.  2000-5000 files in typical small sites.  10,000+ files in large sites with complex plugins  Database can be infected. 5
  7. 7. © 2017 Rick Radko, r3df.com Even more reasons you need a backup Updates:  Bugs  Incompatibility  Update fails to complete 6
  8. 8. © 2017 Rick Radko, r3df.com If you lost your WordPress site, how long would it take you to rebuild? a) Minutes – because I have reliable backup. b) Hours. c) Days. d) Weeks. 7
  9. 9. © 2017 Rick Radko, r3df.com Reconstructing a site without a backup Even small sites take significant effort to recover… Rebuild the WordPress install:  Plugins  Theme  Customizations?  Content 8
  10. 10. © 2017 Rick Radko, r3df.com Reconstructing content Recovering content:  Google, Bing etc. may have cached copies, if you lost the site recently.  Get them immediately! (save as html files)  A lot of cut and paste and editing work.  Re-uploading images. Rebuilds cost: $$ and lost uptime. 9
  11. 11. © 2017 Rick Radko, r3df.com Why back up? Summary The most expensive backup is the one you didn’t do! 10
  12. 12. © 2017 Rick Radko, r3df.com What to back up? 11
  13. 13. © 2017 Rick Radko, r3df.com What to back up? To completely back up a WordPress website, you need: 1. Acopy of the database - Which stores:  All of your site content.  Settings and config for WordPress, plugins and themes. 2. A copy of the files:  All WordPress files, plugin files, theme files. Or  Just the wp-content folder:  Images & other added data 12
  14. 14. © 2017 Rick Radko, r3df.com That’s a lot of data! Backups can be pretty big:  A complete backup of:  An empty WordPress install is about 6 MB  Average sites are 30-100 MB  Large sites in the 100’s of MB. 13
  15. 15. © 2017 Rick Radko, r3df.com Partial back ups Some back-up systems will let you take a ”partial” or “incremental” backup.  Only saves the changes since the last backup.  Reduces data to save.  Increases restore complexity.  Higher risk of a corrupted backup. 14
  16. 16. © 2017 Rick Radko, r3df.com Database dominant If you don’t do any file or media uploads* - only your database is changing and you can:  Back up your database regularly.  Back up your files only when they change. Each database backup will pair with the last file backup, until changes are made to the files. * Embeds (Youtube etc.) are not uploads. 15
  17. 17. © 2017 Rick Radko, r3df.com What to back up? Summary  Everything  Partial or incremental  Database dominant 16
  18. 18. © 2017 Rick Radko, r3df.com When to back up? 17
  19. 19. © 2017 Rick Radko, r3df.com When to back up? For regular backups consider:  The amount of data being added routinely:  Your posting frequency.  Visitor contribution frequency.  How critical your site is.  How big the site is.  Amount of data that needs to be moved and stored. 18
  20. 20. © 2017 Rick Radko, r3df.com When to back up continued? Extra backups for:  Significant change.  WordPress, plugin or theme updates.  Site overhaul or new content launch Plan for the unexpected. 19
  21. 21. © 2017 Rick Radko, r3df.com When to back up? Summary The decision to back up daily, weekly or monthly:  depends on how much you are willing to loose… 20
  22. 22. © 2017 Rick Radko, r3df.com Where to back up? 21
  23. 23. © 2017 Rick Radko, r3df.com Where to back up Off of your server!  A backup on your server:  Does not help with server failures.  A backup file on your server could be a security issue. 22
  24. 24. © 2017 Rick Radko, r3df.com Where to back up continued… Other points:  Off site (different physical location).  Keeping 3 separate copies is recommended.  At least one at a different location!  Backup history – a period of older copies.  Week of daily backups + 2 monthly backups. 23
  25. 25. © 2017 Rick Radko, r3df.com Getting the backup off of the server FTPis an option, but you need a place to FTPto:  A common idea is to use another hosting account somewhere.  Most shared hosting does not allow data storage on their servers (read the fine print in your TOS).  Some hosting services offer storage, expensive unless you have volume. (large corporation) 24
  26. 26. © 2017 Rick Radko, r3df.com Better idea: send it to the cloud Many plugins will let you store your backups on one of the many cloud services.  Amazon S3  Dropbox  Google Drive  +More This is a reasonable option for most sites.  Cloud storage fees are quite low.  Off site. 25
  27. 27. © 2017 Rick Radko, r3df.com How much does the cloud cost? Peanuts… 26
  28. 28. © 2017 Rick Radko, r3df.com What, when, where? Summary Ultimately the decision of :  what  when  where to backup your site will involve assessments of risk and possibly compromises. 27
  29. 29. © 2017 Rick Radko, r3df.com How to back up? 28
  30. 30. © 2017 Rick Radko, r3df.com How to back up Lets look at some tools/ methods to do backups. I’ve grouped them into 4 rough categories:  Manual backups  Backup plugins  Backup services  Site managers 29
  31. 31. © 2017 Rick Radko, r3df.com Manual backups Hosting control panel  Most hosting control panels offer a backup option.  Usually not automated.  May not be very granular. (entire account only) File archive and SQL dump:  Compress (zip/archive) your files into an archive.  Dump (export ) your MySQL database. (phpMyAdmin, and other tools)  FTP the files off the server. 30
  32. 32. © 2017 Rick Radko, r3df.com File archive and SQL dump – pros  Very granular – any site/ part of a site you want.  Very reliable, .zip + sql dump is very portable  No special software/ tools needed to export or restore.  Quick for experienced developers taking a “right now” copy. Tip:  Including the date, 2017-04-03, in the names of both the .zip and .sql files, helps keep backup files together. 31
  33. 33. © 2017 Rick Radko, r3df.com File archive and SQL dump – cons  Need some knowledge:  Database imports/ exports.  Some GUI tools: phpMyAdmin.  How to archive/ un-archive (compress, .zip, gzip etc.)  Comfortable with file systems on the server  Often Linux, or Unix variant.  Need additional scripts for site migration.  Simple "search and replace" does not take into account serialized data.  See https:/ / codex.wordpress.org/ Moving_WordPress 32
  34. 34. © 2017 Rick Radko, r3df.com The biggest issue with manual back ups? 33 Making sure it happens! Backups should be automated, or they will not happen regularly.  It’s not a fun task!  We forget, or “don’t have time”
  35. 35. © 2017 Rick Radko, r3df.com Back up plugins There are a lot of choices in plugins for back ups.  Many are free. (wordpress.org)  Some are paid. Key features to look for:  Automated/scheduled backups.  A must if you want backups you can count on.  Manual backups (on demand)  Using the same settings as your automated backups. 34
  36. 36. © 2017 Rick Radko, r3df.com More plugin features:  File/ directory exclusions.  You may have some files you don’t want backed up.  Allows backing up database only, files only or both.  Flexibility in your backup strategy.  Schedule multiple back ups on different timings.  Offers choice of backup locations:  Backups to cloud:  Dropbox, Amazon, Rackspace, Google Drive, Others?  FTPto other servers/ computers 35
  37. 37. © 2017 Rick Radko, r3df.com Restore and migration features Restore features:  No install restores.  Don’t need WordPress installed.  May need a supporting script.  Malware scans.  Database optimization/repair. Site migration:  Important only if you want to move your site to a new domain. 36
  38. 38. © 2017 Rick Radko, r3df.com Multisite issues If you have multisite enabled, consider whether the backup plugin can:  Backup sites individually?  Backup a sub-network?  Restore sites individually?  Restore a sub-network?  Migrate a single multisite site to/from a single site install? 37
  39. 39. © 2017 Rick Radko, r3df.com Some plugins (no order, or recommendation given) On wordpress.org: (freemium)  UpdraftPlus WordPress Backup Plugin  https://wordpress.org/plugins/updraftplus/  BackWPup  http://wordpress.org/extend/plugins/backwpup/  WordPress Backup to Dropbox  http://wordpress.org/extend/plugins/wordpress-backup-to-dropbox/ BackupBuddy - $  http://ithemes.com/purchase/backupbuddy/ 38
  40. 40. © 2017 Rick Radko, r3df.com Back up services When considering a service:  Most of the same features as for plugins need to be considered.  One item that is key:  Where are they storing your files?  Secure – encrypted? 39
  41. 41. © 2017 Rick Radko, r3df.com More on back up services Unlike plugins:  Most of the services cost.  But they include storage.  Threat and malware scanners are common in the services.  Some offer incremental backups.  Only backup what has changed instead of the whole site.  Most don’t store files on your server. 40
  42. 42. © 2017 Rick Radko, r3df.com A couple of services (no order, or recommendation given) VaultPress  From the people who make WordPress  Starts at $9/month ($3.50 personal sites)  http://vaultpress.com/ BlogVault  Starts at $9/month  http://blogvault.net/ 41

  45. 45. © 2017 Rick Radko, r3df.com How to back up? Summary Lots of ways to do backups (some better than others):  Manual backups  Backup plugins  Backup services  Site managers 44
  46. 46. © 2017 Rick Radko, r3df.com Final Points 45
  47. 47. © 2017 Rick Radko, r3df.com Test your backup flow! Test your backups!  Backups only work if you can restore!  Back up a test site and try restoring it.  Periodically:  Make sure that automated back-ups are still running.  Check that you can actually restore your backups. Try new backup plugins on a test site, not your live site! 46
  48. 48. © 2017 Rick Radko, r3df.com WordPress cron – (or why doesn’t my back up run on time) To automate backups, plugins need something to tell them to run. Unix/ Linux Cron:  Runs at set time, or on regular intervals based on the server clock, but needs separate setup. WordPress Cron:  Triggered by visits to your site, NOT a clock!  A WordPress cron job, set for 1am, may not happen until hours later. 47
  49. 49. © 2017 Rick Radko, r3df.com One final note on backups Backup is often not spelled correctly, a bit of Googling reveals that: The verb form is back up in two words, whereas the noun is backup.  Did you back up the hard drive?  Where did you store the backup? 48
