Old backup and recovery method¶
Note
Our Backups and recovery guide is the most robust method for backup and restoration.
This guide is very similar but uses a different DB backup method, which is known to be problematic in certain scenarios.
This guide is for performing a backup of and restoration of a Canopy instance. Be it for recovery purposes or migration to a new server.
Exporting/Backup on the source server (as root):¶
Stop Canopy services:
root@source:~# systemctl stop canopy canopy-celery
Create a database dump:
root@source:~# canopy-manage dumpdata --all --indent 1 -o /tmp/canopy_db.json
Archive configuration and data files:
root@source:~# tar -zcvf /tmp/canopy_files.tgz /etc/canopy /var/opt/checksec/canopy
Start the services again if this is only a backup. For migrations it’s best to leave them stopped so that the dataset doesn’t diverge due to usage:
root@source:~# systemctl start canopy canopy-celery
For backup purposes store
/tmp/canopy_db.json
and/tmp/canopy_files.tgz
in a safe place.For migration, copy
/tmp/canopy_db.json
and/tmp/canopy_files.tgz
to the target server’s/tmp/
directory.
Warning
The use of the /tmp/
directory is important as canopy-manage
always
runs as the canopy
user and won’t be able to access the same directories
as the root user. Any directory that the canopy
user has access to can be
used.
Importing/Restoring on the target server (as root):¶
Warning
These steps should be performed on a clean server as some of the steps will
delete existing Canopy data. If the target server already has a Canopy
installation then its data directory (/var/opt/checksec/canopy
) should be
removed (or moved).
If installed, remove any installed Canopy package:
root@target:~# apt remove canopy or root@target:~# yum remove canopy
Install the same version of Canopy as the source server. Some additional steps may be required, please see our Installation guide. The DB initialisation and superuser creation steps should be skipped:
root@target:~# apt install canopy.deb # and some installation more steps or root@target:~# yum install canopy.rpm # and some installation more steps
Stop Canopy services:
root@target:~# systemctl stop canopy canopy-celery
Extract Canopy configuration and data files:
root@target:~# tar -xvf /tmp/canopy_files.tgz -C /
Verify/Edit
/etc/canopy/canopy.ini
to ensure it’s valid for the target server.Create and import the DB dump:
root@target:~# canopy-manage setupdb --delete-all --fixture /tmp/canopy_db.json
Run post installation script:
root@target:~# canopy-manage postinstall
Start Canopy services:
root@target:~# systemctl start canopy canopy-celery
Now you can login to the new server and verify that the data is there.
Note
If for some reason the file and directory ownerships are incorrect, they can be reset using (as root):
chown -Rh root:canopy /etc/canopy
chown -Rh canopy: /var/opt/checksec/canopy
chmod -R uog-rwxXst,u=rwX,g=rX /var/opt/checksec/canopy /etc/canopy
