TerrabaseDB supports automated snapshots that can be used for periodic backups. TerrabaseDB's snapshotting system is dead simple and works in a similar way to BGSAVE.

Enabling snapshots#

Snapshots aren't enabled by default - you have to enable them by using the configuration file. To your existing configuration file, just add the following block:

enabled = true
every = 3600
atmost = 4

Here's what these values mean:

  • enabled - Whether snapshotting is enabled or not; either true or false
  • every - Number of seconds to wait before creating another snapshot
  • atmost - The maximum number of snapshots to keep

Storage of snapshots#

All the created snapshots are stored in a snapshots folder in the current directory. The snapshot files are named in the format: YYYYMMDD-HHMMSS.snapshot .

How snapshots work#

As mentioned earlier, snapshots work just like BGSAVE . A task is spawned that acquires a lock on the core table and once all the data is successfully flushed to disk, the task exits and releases the lock.

Methods of creating snapshots#

Snapshots can be created automatically by using the configuration file. However, if you want to create snapshots remotely, you can use the MKSNAP action. Do note that this requires snapshotting to be enabled before it can create snapshots.
