Troubleshoot backups
A backup can fail for any of the following reasons:
Insufficient disk space
If the backup failed because of insufficient disk space, you should typically free up disk space by moving some files to another storage device or drive. However, there might be other ways to resolve the issue. See one of the following resources for tips:

Backup fails
If the backup fails or if all backup tests fail, it鈥檚 possible the Magento file system owner doesn鈥檛 have sufficient privileges and ownership of the Magento file system. For example, another user might own the files or the files might be read-only.
Pay particular attention to file system permissions and ownership of the <your Magento install dir>/var directory and subdirectories. For more information, see Set file system permissions and ownership.
