![]() Once again, the general limitations are your outbound bandwidth, and the cost of storage. I've had multiple scripts over the years, and they all fell a bit short, which is generally why I haven't posted them.)įor UNIXy systems, there are multiple providers that use rsync with ssh to back up, such as tarsnap. ![]() (For ZFS, I am still trying to figure out the best way to automate this. There are quite a few other options for this, and plenty of similar options for Windows as well. arq uses a cloud provider of your choice, while Backblaze backs up to Backblaze's cloud. ![]() For my Macs, for example, I use arq and Backblaze. The easiest, by far, way to do this is to use one of many possible cloud backup applications. (Time Machine allows you to encrypt the disk with FreeBSD, you can use GELI to do the same, or you can use an encrypted ZFS dataset.)Īnother way to do remote backups is to use the cloud. For the latter two, it's recommended that you encrypt your backup somehow. Remember that once it's not in your control, it can be damaged, accessed, or stolen. To a friend's house, or to a safe deposit box, or any number of storage idea. To your office (or to your home, if you're backing up at the office). With macOS, that would most likely be a Time Machine volume on an external disk with traditional Unix, you could use backup or rsync to a tape (yes, I am old), or to an external or removable disk. The simplest way to do a remote backup is to simply do a backup to a local removable disk. The main limitation is bandwidth and storage capacity.) ![]() (As I am a big fan of ZFS, you can do replication both to another host on your local network, or across the globe. This can be done by taking an existing backup offsite, or backing up to a destination using a network. As usual, most of my focus is on unix and macOS, although Windows generally has equivalents for everything.Ī remote backup is, as the name implies, a backup that is not local to you. This time, I am going to discuss remote backups, and several types of that. (I only barely touched the surface on that, but I'm mostly focusing on automatic, mostly-full backups, as opposed to manually making copies of individual files.) Previously, I discussed why backups are important, and the various kinds of backups that exist. ![]()
