I wrote earlier about how to backup a small SQLite database. That solution works well for small databases, but can become impractical for larger databases. In particular if the machine with the database has not enough disk space for another copy of it, and you want to backup to another machine. One option is to use sqlite3_rsync, but I could not get that to work, it kept running out of memory.

As I mentioned earlier, it’s straightforward to use SQLite as the relational database in Go applications. Your data is stored in one single file with a well-defined format and there is no hassle with installing and configuring a separate database. However, for any serious application you most likely want backup of your data. If your dataset is not very large, and it is OK to lose updates since the last backup, there is a very simple option.
