Backup and Restore

Backup and restore on Windows

For Docker/Linux and Kubernetes instructions, see Backup and Restore in Docker.

Seq creates daily backups of metadata and configuration, including API keys, users, signals and apps. Events are not backed up by this process - use the replication, JSON archive or file archive apps for redundant event storage if necessary.


Encrypted Storage

To protect sensitive information, Seq applies AES-256 encryption to backup files.

An encryption key is required when restoring backups: please ensure you follow the instructions below for retrieving and storing the encryption key.

Obtaining the Secret Encryption Key

Seq backups are encrypted using AES-256, with a key stored in Seq.json. On Windows, the value in the configuration file is protected using DPAPI, so it cannot be backed up directly.

To obtain the secret key on Windows, open an administrative command prompt on the Seq server machine and invoke:

seq show-key

The key is a base-64 encoded value. Save this in a secure location so that backups can be restored.


Each named Seq instance has a unique secret key. Specify the instance name with -n name.

Automatic Backup

Seq will automatically back up configuration on a daily basis. The .seqbac files created are stored in the Backups/ directory under the Storage root path.

Backups can be retrieved directly from disk, or downloaded from the web UI in Settings > Backups.


Seven days of backups will be retained, after which Seq will delete the oldest backup file when new backups are created.

Configuring Backup

Backup settings can be customized in Settings > Backup > Backup Settings.


When specifying the time of day at which to back up, UTC is used.

Restoring from Backup


Quick rollback

Want to restore a Seq instance from its own latest nightly backup? Skip the --secret-key, --backup, and --enable-apps flags by specifying --from-latest on the seq restore command-line instead:

seq service stop
seq restore --from-latest
seq service start

To restore from a backup:

  1. Install Seq on the new machine. The version must be identical to the one used when creating the backup. Contact support if you need assistance locating this.
  2. Start Seq so that the default configuration is created and data storage initialized.
  3. On the Seq server machine, at an administrative command prompt, run the series of commands below.
seq service stop
seq restore --secret-key="1234567abcdef=" --backup="C:\Data\seq_20150101.seqbac"
seq service start

All commands require the -n parameter if named instances are in use.


Enabling Apps on Restored Instances

To avoid accidentally triggering production apps and alerts when testing backups, the restore process by default sets all Seq App instances to manual input only.

To change this behavior, pass --enable-apps to the seq restore command. Otherwise, apps will need to be manually re-enabled through the user interface once the Seq server has been restored.
