- Not a bug as such, but one issue to be aware of is that backups of very large sites (lots of uploaded media) are quite complex matters, given the limits of running inside WordPress on a huge variety of different web hosting setups. With large sites, you need to use Amazon S3, which UpdraftPlus supports (since 0.9.20) or Google Drive (since 0.9.21) or Dropbox (since 1.2.19), because these support chunked, resumable uploads. Other backup methods have code (since 0.9.0) to retry failed uploads of an archive, but the upload cannot be chunked, so if an archive is enormous (i.e. cannot be completely uploaded in the time that PHP is allowed for running on your web host) it cannot work.

  == Upgrade Notice ==
11
+ Everything now resumable: every part of a backup run can now be individually resumed, meaning that there are no theoretical limits imposed by any part of the UD architecture upon the size of your backup. (This was the final step: with previous steps, probably only 0.1% of WordPress sites were still "too large" for the remaining bottleneck).

64
+ Authors of backup plugins will tell you that writing a reliable plugin that can run in the whole variety of WordPress environments is hard. Now, since version 1.4.0, UpdraftPlus has an architecture that can back up infinitely large sites. It can now resume at *any* stage of the backup. Wherever your web server terminates your backups due to its limits (on CPU usage, available time to run in, etc.), UpdraftPlus can pick up again and carry on. Do be aware though that you need enough disk space free in your web hosting account to create the backup in. Exactly how much is needed can vary; but you are always safe if you have as much space available as your website takes up (i.e. can temporarily double your disk usage).
