On rundeck backup guide, noted that is mandatory to stop rundeck to take full backup when using data file. Now, that guide don't show any secure method to backup full rundeck instance (rundeck server + database) when using MariaDB, PostgreSQL, or any supported database as a backend.
In a real production scenario, not seems to be possible to stop rdeck on a daily basis.
Can anybody share best pratices to take a hot full backup on rdeck installation without stop rdeck?
Is there any secure and supported way to achive a full consistent rdeck projects and jobs definitions and database on a daily basis ?
In this post, answer is not clear, because question don't describe what kinbd of backend are used.
The documentation suggests the instance shutdown because some execution could be active, and that means a potentially active transaction in the middle of the "hot backup process" which means a potential data corruption in your backup. Is the safest way to backup your database.
If you want to do a "hot" backup you can export your projects (with all content, including jobs) and keys.

I am using Rundeck Docker Container. It was running well for 2 months and suddenly it crashed. I lost all the data wrt a project that I had created using CLI. Is there a way to change the default path to store all project related data including job definitions, resources etc?
Out of the box, Rundeck stores the project/jobs data on their internal H2 database, this database is only for testing purposes and probably will crash with a lot of data (storing projects at filesystem is deprecated right now), the best approach is to use a "real" database like MySQL, PostgreSQL, or Oracle, in that way Rundeck stores all project/jobs data on a robust backend.
Check this MySQL, PostgreSQL and Oracle Docker environment examples.
Of course, having a backup policy for your instance would be ideal to keep safe all your instance data.
Build servers are generally detached from the VPC running the instance. Be it Cloud Build on GCP, or utilising one of the many CI tools out there (CircleCI, Codeship etc), thus running DB schema updates is particularly challenging.
So, it makes me wonder.... When's the best place to run database schema migrations?
From my perspective, there are four opportunities to automatically run schema migrations or seeds within a CD pipeline:
Within the build phase
On instance startup
Via a warm-up script (synchronously or asynchronously)
Via an endpoint, either automatically or manually called post deployment
The primary issue with option 1 is security. With Google Cloud Sql/Google Cloud Build, it's been possible for me to run (with much struggle), schema migrations/seeds via a build step and a SQL proxy. To be honest, it was a total ball-ache to set up...but it works.
My latest project is utilising MongoDb, for which I've connected in migrate-mongo if I ever need to move some data around/seed some data. Unfortunately there is no such SQL proxy to securely connect MongoDb (atlas) to Cloud Build (or any other CI tools) as it doesn't run in the instance's VPC. Thus, it's a dead-end in my eyes.
I'm therefore warming (no pun intended) to the warm-up script concept.
With App Engine, the warm-up script is called prior to traffic being served, and on the host which would already have access via the VPC. The warmup script is meant to be used for opening up database connections to speed up connectivity, but assuming there are no outstanding migrations, it'd be doing exactly that - a very light-weight select statement.
Can anyone think of any issues with this approach?
Option 4 is also suitable (it's essentially the same thing). There may be a bit more protection required on these endpoints though - especially if a "down" migration script exists(!)
It's hard to answer you because it's an opinion based question!
Here my thoughts about your propositions
It's the best solution for me. Of course you have to take care to only add field and not to delete or remove existing schema field. Like this, you can update your schema during the Build phase, then deploy. The new deployment will take the new schema and the obsolete field will no longer be used. On the next schema update, you will be able to delete these obsolete field and clean your schema.
This solution will decrease your cold start performance. It's not a suitable solution
Same remark as before, in addition to be sticky to App Engine infrastructure and way of working.
No real advantage compare to the solution 1.
About security, Cloud Build will be able to work with worker pool soon. Still in alpha but I expect in the next month an alpha release of it.
When I take a backup of a database (SQL Server), is there any way that I can include a scheduled job in the backup?
I have a database with stored procedures and a maintenance job that runs some of the stored procedures nightly.
I would like to achieve a minimal effort to schedule the job, when the .bak file is restored into a server, back as a database.
I don't have the quick button to click for your problem, but I think (not sitting in front of it right now) You can right click a job and get a script for its creation including scheduling specifics. I don't know how to include a job in a backup and how to restore it, though. I think restoring a job would require a script with the CREATE for the job to be run.
You can also back up the msdb database. The msdb database is where all the jobs live, it is one of the system databases, and then restore your database plus msdb.
I have been using PG Backups add-on recently and everything has worked fine, however this morning the backup process triggered at 10:00 A.M. in the morning generating some blocks and timeouts in my application.
Is there a way to specify the schedule of the backups made with this add-on? I've been searching and haven't found anything specific.
Use Cron for Manual Backup Scheduling
Heroku gives you two types of backups: automated and user-initiated. Each plan has a different number of daily, weekly, and manual backups that are retained. You can't control when the automated backups occur with PG Backups Auto, but you can use cron to trigger a "manual" backup at any time.
For example:
# Trigger a "manual" backup every four hours.
0 */4 * * * source $HOME/database_credentials; heroku pgbackups:capture
See Creating a Backup for more information about using the pgbackups command.
No, there is no way to do it currently, aside from using an external process to fire the calls.
An email to support might reveal more.
While the original question is old, Heroku does have a schedule option for PGBackups now:

We have a 5 node replication set up on our development server. We are looking for a way to allow developers to back up a subset of data in a mongo db and restore this to their local development enviroments.
We have looked into the clonedb and the mongodump utils, but both only allow for a backup/dump of the complete database. Due to the possible size of the database, we need an option that allows us to limit the data being backed up or restored.
Do any know of a util or way to achieve this?
I just stumbled upon this question again and decided to add a description of our backup strategy we opt in for:
Current back up strategy for our mongo db this server consist of 2 setups; backup via delayed passive secondarynode and daily backup using mongodump (takes journalling and oplog into play).
Besides our normal production nodes, we have setup another secondary node with a priority of 0 (this can either be on its own server or piggy backing off another mongo server but using a seperate port), hidden as true and a delay of 7200 seconds (2hours). This slave is there for "butter fingers", when some one accidentally drops a database or clears a collection, we have 2 hours before these changes replicate to this passive secondary. The passive secondary can NOT be used for READING or WRITING. It's role is simply a back up node. We also use this node for nightly backup to prevent unnecessary overhead on any of the other nodes.
The nightly backup is set to run every night at 23:00 via a cron tab. The command simply executes a script setup in /opt/auto-mongo-backup. This script can be found at https://github.com/jaconel/automongobackup (originally found it at https://github.com/micahwedemeyer/automongobackup). This script allows for a single nightly cron to cover weekly backups and monthly backups. Back ups are saved at /var/backups/mongodb.
Hope this helps some one out.
