Storing backups on one site
Send your backups to an offsite service like Solid Backups Stash, any FTP server or an Amazon S3 account. If your site goes down, your backups will not go down with it.
Sending large backup files via email
Consider this: each backup file can be several hundred megabytes in size. Email accounts may have restrictions on attachment size and storage limits. Send only small backups to email (such as Database Only backups). Larger backups files should be sent offsite to BackupBuddy Stash, Dropbox or an Amazon S3 account.
Relying solely on Solid Backups Database Only backups
A Solid Backups Database Only backup backs up your database, but it does not contain any WordPress configuration files, themes or plugins. Only a Solid Backups Complete Backup includes all files and the entire database necessary for a complete migration or site restore.
Uploading the Standalone Importer file without the backup file
Restoring or migrating your site requires both the Standalone Importer script and the backup file.
Uploading the Standalone Importer file into a different directory than the backup file
The backup file should be uploaded to the same directory as the Standalone Importer file. In other words, don’t put the files in a subdirectory if the site is to be on the root domain.
