Note that it does do a proper backup. If it doesn’t, please add version info and other details as described in Having problems with UrBackup? Please read before posting .
It even does a integrity check before it backs up the database. Of course this does not check everything. If you use disks/storage controllers which corrupt data run it on file systems such ZFS or btrfs which do detect corruption and can correct it.
If you want versioned backups, or have a larger database, the usual advice is to install the UrBackup client on the server itself and configure it to backup the database.
