-At the trigger time, the `prodDBBackupHandler` function is called, executing the desired business logic for this job at trigger time. For example:

-#### HTTP
-
-When you create a job using Dapr's Jobs API, Dapr will automatically assume there is an endpoint available at 
-`/job/<job-name>`. For instance, if you schedule a job named `test`, Dapr expects your application to listen for job 
-events at `/job/test`. Ensure your application has a handler set up for this endpoint to process the job when it is 
-triggered. For example:
-
-*Note: The following example is in Go but applies to any programming language.*
-
-```go
-
-func main() {
-    ...
-    http.HandleFunc("/job/", handleJob)
-	http.HandleFunc("/job/<job-name>", specificJob)
-    ...
-}
-
-func specificJob(w http.ResponseWriter, r *http.Request) {
-    // Handle specific triggered job
-}
-
-func handleJob(w http.ResponseWriter, r *http.Request) {
-    // Handle the triggered jobs
-}
-```
-
-#### gRPC
-
-When a job reaches its scheduled trigger time, the triggered job is sent back to the application via the following 
-callback function:
-
-*Note: The following example is in Go but applies to any programming language with gRPC support.*
-
-```go
-import rtv1 "github.com/dapr/dapr/pkg/proto/runtime/v1"
-...
-func (s *JobService) OnJobEventAlpha1(ctx context.Context, in *rtv1.JobEventRequest) (*rtv1.JobEventResponse, error) {
-    // Handle the triggered job
-}
-```
-
-This function processes the triggered jobs within the context of your gRPC server. When you set up the server, ensure that 
-you register the callback server, which will invoke this function when a job is triggered:
-
-```go
-...
-js := &JobService{}
-rtv1.RegisterAppCallbackAlphaServer(server, js)
-```
-
-In this setup, you have full control over how triggered jobs are received and processed, as they are routed directly 
-through this gRPC method.
-
-#### SDKs
-
-For SDK users, handling triggered jobs is simpler. When a job is triggered, Dapr will automatically route the job to the 
-event handler you set up during the server initialization. For example, in Go, you'd register the event handler like this:

+---
+
+Now that you've learned about the [jobs building block]({{< ref jobs-overview.md >}}) at a high level, let's deep dive 
+into the features and concepts included with Dapr Jobs and the various SDKs. Dapr Jobs:
+- Provides a robust and scalable API for scheduling operations to be triggered in the future.
+- Exposes several capabilities which are common across all supported languages.
+
+
+
+## Job identity
+
+All jobs are registered with a case-sensitive job name. These names are intended to be unique across all services 
+interfacing with the Dapr runtime. The name is used as an identifier when creating and modifying the job as well as 
+to indicate which job a triggered invocation is associated with.
+
+Only one job can be associated with a name at any given time. Any attempt to create a new job using the same name
+as an existing job will result in an overwrite of this existing job.
+
+## Scheduling Jobs
+A job can be scheduled using any of the following mechanisms:
+- Intervals using Cron expressions, duration values, or period expressions
+- Specific dates and times
+
+For all time-based schedules, if a timestamp is provided with a time zone via the RFC3339 specification, that 
+time zone is used. When not provided, the time zone used by the server running Dapr is used. 
+In other words, do **not** assume that times run in UTC time zone, unless otherwise specified when scheduling
+the job.
+
+### Schedule using a Cron expression
+When scheduling a job to execute on a specific interval using a Cron expression, the expression is written using 6
+fields spanning the values specified in the table below:
+
+| seconds | minutes | hours | day of month | month | day of week |
+| -- | -- | -- | -- | -- | -- |
+| 0-59 | 0-59 | 0-23 | 1-31 | 1-12/jan-dec | 0-6/sun-sat |
+
+#### Example 1
+`"0 30 * * * *"` triggers every hour on the half-hour mark.
+
+#### Example 2
+`"0 15 3 * * *"` triggers every day at 03:15.
+
+### Schedule using a duration value
+You can schedule jobs using [a Go duration string](https://pkg.go.dev/time#ParseDuration), in which
+a string consists of a (possibly) signed sequence of decimal numbers, each with an optional fraction and a unit suffix. 
+Valid time units are `"ns"`, `"us"`, `"ms"`, `"s"`, `"m"`, or `"h"`.
+
+#### Example 1
+`"2h45m"` triggers every 2 hours and 45 minutes.
+
+#### Example 2
+`"37m25s"` triggers every 37 minutes and 25 seconds.
+
+### Schedule using a period expression
+The following period expressions are supported. The "@every" expression also accepts a [Go duration string](https://pkg.go.dev/time#ParseDuration).
+
+| Entry | Description | Equivalent Cron expression |
+| -- | -- | -- |
+| @every | Run every (e.g. "@every 1h30m") | N/A |
+| @yearly (or @annually) | Run once a year, midnight, January 1st | 0 0 0 1 1 * |
+| @monthly | Run once a month, midnight, first of month | 0 0 0 1 * * |
+| @weekly | Run once a week, midnight on Sunday | 0 0 0 * * 0 |
+| @daily or @midnight | Run once a day at midnight | 0 0 0 * * * |
+| @hourly | Run once an hour at the beginning of the hour | 0 0 * * * * |
+
+### Schedule using a specific date/time
+A job can also be scheduled to run at a particular point in time by providing a date using the 
+[RFC3339 specification](https://www.rfc-editor.org/rfc/rfc3339).
+
+#### Example 1
+`"2025-12-09T16:09:53+00:00"` Indicates that the job should be run on December 9, 2025 at 4:09:53 PM UTC.
+
+## Scheduled triggers
+When a scheduled Dapr job is triggered, the runtime sends a message back to the service that scheduled the job using
+either the HTTP or gRPC approach, depending on which is registered with Dapr when the service starts.
+
+### gRPC
+When a job reaches its scheduled trigger time, the triggered job is sent back to the application via the following
+callback function:
+
+> **Note:** The following example is in Go, but applies to any programming language with gRPC support.
+
+```go
+import rtv1 "github.com/dapr/dapr/pkg/proto/runtime/v1"
+...
+func (s *JobService) OnJobEventAlpha1(ctx context.Context, in *rtv1.JobEventRequest) (*rtv1.JobEventResponse, error) {
+    // Handle the triggered job
+}
+```
+
+This function processes the triggered jobs within the context of your gRPC server. When you set up the server, ensure that
+you register the callback server, which invokes this function when a job is triggered:
+
+```go
+...
+js := &JobService{}
+rtv1.RegisterAppCallbackAlphaServer(server, js)
+```
+
+In this setup, you have full control over how triggered jobs are received and processed, as they are routed directly
+through this gRPC method.
+
+### HTTP
+If a gRPC server isn't registered with Dapr when the application starts up, Dapr instead triggers jobs by making a 
+POST request to the endpoint `/job/<job-name>`. The body includes the following information about the job:
+- `Schedule`: When the job triggers occur
+- `RepeatCount`: An optional value indicating how often the job should repeat
+- `DueTime`: An optional point in time representing either the one time when the job should execute (if not recurring)
+or the not-before time from which the schedule should take effect
+- `Ttl`: An optional value indicating when the job should expire
+- `Payload`: A collection of bytes containing data originally stored when the job was scheduled
+
+The `DueTime` and `Ttl` fields will reflect an RC3339 timestamp value reflective of the time zone provided when the job was
+originally scheduled. If no time zone was provided, these values indicate the time zone used by the server running
+Dapr.
