Backup/Migration is slow
Here are two main causes of a slow backup process: 1. The disk I/O of the web hosting is slow. We have noticed that the disk IO of many web hosting is only 1MB/s, then theoretically backing up a 100MB website would require at least 300s. You can check the disk I/O of...
Backup size is different from the website size
During the backup process, our plugin will compress your website data into zip files to save storage space. So it is normal that your website is, for example, 5 GB(the calculation result on WPvivid backup page) while the backup will be only 1GB. You can verify a...
Get Apache2 Ubuntu Default Page after migration

When creating a backup it breaks into several parts
That is because by default, our plugin splits a backup to multiple parts(200MB for each) to increase backup success rate, especially for websites with shared web hosting. However, you do have the option to finally get a single backup file by changing the following...
