One way of supplying such functionality for file-based data exchange is through the use of archiving functionality. With the help of this functionality can you easily write the file as received (or about to be sent) to a separate location. By ensuring that the data stays in that location for a certain amount of time and by giving the customer and yourself access you have a sort of audit trail that details the messages that have been exchanged. This archive could also be used to analyze problems in case things go wrong. In this microlearning, we will learn how you can set up that archiving and learn how to clean up the archiving to ensure that data is only kept for a limited period. 3 3 3 +When you need to read and write files from an on-premise disk, you need to know the path in which the data is stored and make sure that the docker container in your runtime(s) running has access to this path.

But before we do, we first explain how to set up this configuration within eMagiz. Then, you must navigate to Deploy -> Architecture on the model level. In this overview, you can access the Volume mapping per runtime deployed on-premise. To do so, you can right-click on the runtime to access the context menu. 30 30 31 -[[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity-a rchiving--file-name-generator.png]]35 +[[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity-volume-mapping-on-premise--volume-option-context-menu.png]] 32 32 33 - After wehavedonethis please add a fileoutboundchanneladapterto the flowcludingan inputchannel.Ensure thatyou use apropertyfor thedirectorythatreferencesanotherdirectorycomparedtothe inputdirectorytopreventcreatingan infiniteloop.37 +When you click this option, you will see the following pop-up. In this pop-up, you can define the machine-level and runtime-level volumes. More on that later. This is the starting point for configuring your volume mapping. We will walk through each available option and explain how they work and should be configured. 34 34 35 -[[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity- archiving--archiving-config-file-outbound-basic.png]]39 +[[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity-volume-mapping-on-premise--volume-mapping-pop-up.png]] 36 36 37 -No wthatwehave configuredthebasics letus turn our attention totheadvancedconfiguration.In the advancedtabofthis component,weneedto select the file namegeneratortoensurethat thefiles are namedcorrectly.

Note that this samepieceof logiccould be applied inother flows within the eMagiz platform ina similar manner.45 +The first Type available to you is Volume. With this option, you create one or more folders on Docker relevant to that runtime to read and write **persistent** data. To configure this Type, you need to link the runtime volume to a machine volume you can create within the same pop-up. This means you can re-use a "Machine volume" over multiple runtimes (i.e., containers). 42 42 43 - [[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity-archiving--archiving-result.png]]47 +So, we first open the tab called "Machine volume." Then, by pressing the "New" button, we can define a new "Machine volume." In the pop-up that follows, we can specify the name of a machine volume and tell whether the Volume already exists on your docker installation or not. 44 44 45 - === 3.2 CleanuptheArchive===49 +[[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity-volume-mapping-on-premise--machine-volumes-configuration.png]] 46 46 47 - To ensurethatthe dataisnotkeptindefinitelywe need tocleanupthearchive.We dootopreventproblemswithdisk space butalso toprevent data leaksof old datathatcouldimpact theprivacyof others.Before we cansetup the logic ineMagizwe need totalktothecustomerto seewhatanacceptabletermiswithinwhichthedata iskept.Inmostcases, this is a weekortwo weeks.

In the following pop-up, we first need to select the Type we want to use. For this example, we use the Type called "Volume." Based on your selection, the relevant input fields will change. 48 48 49 - Now that weknow the limit it istime toconfigurethe components. We start with a compositefilter (support object).

Once we have chosen our "Machine volume," we must set the Target specific for this runtime. This target defines the second part of the path to which the runtime will gain access. For example, when you fill in "/target", we can combine this with the "Machine volume" name to arrive at the correct directory from which eMagiz needs to read data (or write data to). So in our case, this would be "/file-directory/target." 52 52 53 - Havingdone sowecanaddafile inbound channeladapterothecanvasincludingan outputchannel.Ensurethat thepropertyreference forthedirectory matches theoneyouhaveusedbefore intheoutboundchannel adapter.Furthermore linkthefilterto thecomponentanddefinethepoller accordingto the best practice.57 +The last setting we need to configure is to define which rights we will grant our runtime on the Volume we are creating. The default setting is read/write rights for the runtime, which is sufficient in most cases.

In general, we advise using the "Volume" option because they have better performance, and bind mounts depend on the host machine's directory structure and OS. However, only some external systems can adapt to this that easily. For example, the "Bind mount" option can interest your use case. 62 62 63 -[[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity-a rchiving--archive-cleanup-deletion.png]]67 +[[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity-volume-mapping-on-premise--runtime-volumes-configuration-type-bind-mount.png]] 64 64 65 -T hiswillensure that eachfile thatis retrievedwill indeed be deleted fromthearchive.69 +To configure a "Bind mount," you need to define a source and a target directory linked to each other. The source directory represents the directory on your local system (that might already be used currently to exchange files). The target directory defines a directory on your docker installation that the runtime can access. 66 66 71 +{{warning}}Note that when the source directory does not exist, the runtimes cannot be deployed correctly.{{/warning}} 72 + 73 +[[image:Main.Images.Microlearning.WebHome@novice-file-based-connectivity-volume-mapping-on-premise--runtime-volumes-configuration-type-bind-mount-filled-in.png]] 74 + 75 +{{info}}Note that when you use this option, your directory reference in your flow should refer to the "target" directory configured here.{{/info}} 76 + 77 +=== 3.3 Temporary file system === 78 + 79 +The temporary file system option is for you if you do not want to work with **persistent** data but require **non-persistent** data.
