+ | |||
+ | |||
+ | * When you use a (long) public link for sharing data, you may want to use an URL shortening service to make things easier (e.g. [[https://bitly.com/|bitly]]) | ||
+ | * **Do not** use a URL shortening service to share **confidential information**! | ||
+ | |||
+ | * With some work, you can use [[https://rclone.org/|rclone]] on the LSCE servers to move files directly from one of the LSCE servers to sharebox ! | ||

- | ===== Synchronizing folders ===== | + | ==== Creating a folder synchronization ==== |
+ | |||
+ | * Create your main [[other:win10config#the_most_important_folders|OWNCLOUD folder]] on the **local computer**:\\ e.g. ''<some_disk_different_from_c>:\Users\<your_login>_owncloud'' | ||
+ | * Use the web interface to create your main ownCloud folder the //sharebox// **remote server**:\\ e.g. ''Backup/<your_login>_owncloud''{{ :other:sharebox_folders_notes.png?direct&600 |}} | ||
+ | * Open the //ownCloud// interface and click on the ''Add account'' button\\ If you want to add a folder sync to an existing remote server, just select the server and click on ''Add Folder Sync Connection'' | ||
+ | * Use the //sharebox// address (or CNRS //mycore//) in the ''Server Address'' field, and then your LSCE ''Username'' and ''Password'' | ||
+ | * **Be sure to select ''Manually create folder sync connections''** and then click on ''Connect...'' | ||
+ | * You are now ready to connect a **local** folder on your computer to a **remote** folder on //sharebox//! | ||
+ | * Click on ''Add Folder Sync Connection'': | ||
+ | * ''Pick a local folder on your computer to sync'':\\ Select your main local OWNCLOUD folder: ''<some_disk_different_from_c>:\Users\<your_login>_owncloud'' | ||
+ | * ''Select a remote destination folder'':\\ Select your main remote folder: ''/Backup/your_login_owncloud'' | ||
+ | * **Be sure to uncheck the ''Use virtual files instead of donwloading content immediately''** | ||
+ | * Click on ''Add Sync Connection'' to finalize the connection and you should end up with something looking like{{ :other:sharebox_connected_notes.png?direct&600 |}} | ||
+ | |||
+ | ==== Testing a folder synchronization ==== | ||
+ | |||
+ | <note important>It is **very important** to experiment a bit, and understand how the synchronization works!</note> | ||
+ | |||
+ | * create test folders and files in the **local folder** (''<some_disk_different_from_c>:\Users\<your_login>_owncloud'') | ||
+ | * check the content of the matching folder(s) in the **sharebox remote folder** (''/Backup/your_login_owncloud''). You will probably have to **refresh the content of the browser window** (use the ''F5'' button to easily refresh a browser window){{ :other:owncloud_sync_folders_notes.png?direct&600 |}} | ||
+ | * <wrap hi>**Warning! The mirroring works both ways!**</wrap> If you remove files or folders on the sharebox server (using the web interface), they will also be automatically deleted in the local folder! | ||
+ | * Try it for yourself by deleting some test files on the sharebox server | ||
+ | * Warning! When you delete something (locally or on the remote server), it will be moved to the ''Deleted files'' section of the remote server | ||
+ | * This is a useful safety feature, because it allows you to recover files from the trashcan | ||
+ | * It's possible (not sure yet... FIXME) that files in the trashcan may be automatically removed after //some time// (to determine... FIXME) | ||
+ | * The [[other:lsce_cloud#space_management|trashcan may use a lot of space]]! Be sure to clean it regularly! | ||
+ | |||
+ | ==== Checking that things are working correctly ==== | ||
+ | |||
+ | <note important>There shouldn't be any problem, but you should still **check regularly that ownCloud is running correctly** | ||
+ | |||
+ | Quitting (one of the rare times when you should use the ''Quit ownCloud'' button) and restarting ownCloud may take care of problems</note> | ||
+ | |||
+ | === The obvious stuff === | ||
+ | |||
+ | * The mirroring will only work if: | ||
+ | * ownCloud is running on the local computer | ||
+ | * your computer has network access (and is online long enough to send/receive all the changes) | ||
+ | * the sharebox server is running | ||
+ | |||
+ | * Be sure to save the files that you are editing (and that are in a mirrored folder) before shutting down your computer, so that the latest version of the files is sent to sharebox | ||
+ | * use a //long enough// delay after saving a file and shutting down your computer: a few seconds should be OK, depending on the file size and the network access. You can always [[#checking_owncloud_activity|check the activity log]] to be sure | ||
+ | |||
+ | === Is ownCloud running ? === | ||
+ | |||
+ | Check that there is an ownCloud icon in the hidden icons of the taskbar (or start ownCloud) and that it has a green check-mark{{ :other:owncloud_ok.png?direct |}} | ||
+ | |||
+ | **ownCloud should always be running**, unless you have used the ''Quit ownCloud'' by mistake, instead of ''Hide'', in the interface. | ||
+ | |||
+ | === Checking ownCloud status === | ||
+ | |||
+ | You can start the ownCloud interface and **check that ownCloud is operating properly** (//green// check-mark){{ :other:owncloud_status_blank.png?direct&500 |}} | ||
+ | |||
+ | === Checking ownCloud activity === | ||
+ | |||
+ | You can use the ''Activity'' panel to **check the recent activity** and make sure that ownCloud did everything //as expected//. If you see errors, try to correct them as soon as possible! | ||
+ | |||
+ | The most recent action is listed at the top. In the example below (from bottom to top): | ||
+ | * A new folder on the local computer is uploaded to sharebox, and then renamed (''Moved''...) on sharebox after being renamed locally | ||
+ | * A test image is added to the new folder (both locally and on sharebox) and then renamed | ||
+ | * A text file is added, renamed and updated | ||
+ | |||
+ | {{ :other:owncloud_activity_blank.png?direct&600 |}} | ||
+ | |||
+ | === Warnings and errors examples === | ||
+ | |||
+ | A **//blue// status icon is a warning** that there is a problem that you can probably ignore. Check the ownCloud activity panel if you want to be sure! | ||
+ | |||
+ | e.g. the warning you get when all files are mirrored, but some temporary files were automatically ignored {{ :other:owncloud_info_notes.png?direct&800 |}} | ||
+ | |||
+ | If you have forgotten to [[other:lsce_cloud#installation_and_basic_configuration|disable the option]] //Ask for confirmation before synchronizing folders larger than NNN MB//, you //may// get a warning that some folders were not syncronized. Or not... | ||
+ | |||
+ | A **//red// status icon means that there is a problem** that you should investigate and fix | ||
+ | |||
+ | e.g. the error you get when the local folder is not accessible (because it does not exist, is encrypted, etc...) {{ :other:owncloud_error.png?direct&800 |}} | ||
+ | ==== Are you ready? ==== | ||
+ | |||
+ | You should now be ready to add real folders and documents to the [[other:win10config#local_owncloud_folder|local OWNCLOUD folder]] on your computer! | ||
+ | |||
+ | * Don't try doing too much at the beginning... | ||
+ | * i.e start with a simple sub-folder of the [[other:win10config#local_owncloud_folder|local OWNCLOUD folder]], add more folders later when you feel safe | ||
+ | * The storage space is not infinite ([[other:lsce_cloud#space_management|check your storage usage]] from time to time)! | ||
+ | * **Do not** mirror your //Windows// home folder (on ''C:''), or similar folders (e.g. //Thunderbird//, //Firefox// and //Chrome// folders) that have lots and lots of useless cache/temporary files | ||
+ | * To be sure of what you are mirroring, it's safer to create a dedicated [[other:win10config#local_owncloud_folder|local OWNCLOUD folder]] (outside of the other folders you use) and progressively add subfolders that you want to mirror | ||
+ | * Never forget that //mirroring// is not a foolproof type of backup! | ||
+ | * You should also use SyncBack or other types of [[other:win10apps#backup_software|Backup software]] for saving your data to an external disk | ||
+ | * Check from time to time that [[#checking_that_things_are_working_correctly|ownCloud is working as expected]] | ||
+ | ===== Synchronizing folders on different computers ===== | ||
+ | |||
+ | It should be very easy to synchronize folders, **if you have read all the previous sections of this page**! | ||
+ | |||
+ | ==== How does it work ? ==== | ||
+ | |||
+ | Basically, we are just going to use ownCloud, and mirror folders from two (or more) computers to the LSCE | ||
+ | //sharebox// server ! | ||
+ | |||
+ | <WRAP center round box 60%> | ||
+ | Local folder on **computer A** <wrap em><=></wrap> <wrap hi>** Folder on sharebox server**</wrap> <wrap em><=></wrap> Local folder on **computer B** | ||
+ | |||
+ | Example use case: | ||
+ | * **computer A**: computer at work | ||
+ | * **computer B**: computer at home | ||
+ | </WRAP> | ||
+ | |||
+ | A file (or folder) //changed// (created, updated or removed) on **computer A** will: | ||
+ | - be mirrored to the sharebox server | ||
+ | - and then mirrored to **computer B** | ||
+ | |||
+ | This will work seamlessly provided you <wrap em>don't change the same file (or folder) at the same time on different computers !!</wrap> This will be easy to do if you: | ||
+ | |||
+ | * save and close files in mirrored folders before moving from one computer to the other (e.g. before going back home, or going to work) | ||
+ | * make sure the computers are online //long enough// to mirror their files to the sharebox server before switching the computers off | ||
+ | |||
+ | |||
+ | ==== Configuration ==== | ||
+ | |||
+ | - [[other:lsce_cloud#synchronizing_folders_with_owncloud|Install ownCloud and create a folder configuration]] on **computer A** (your main computer) | ||
+ | * e.g. LOCAL folder <wrap em>@ A</wrap>: ''<some_disk_different_from_c_on_A>:\Users\<your_login>_owncloud'' | ||
+ | * e.g. REMOTE: ''Backup/<your_login>_owncloud'' | ||
+ | - Add some content to the LOCAL mirrored folder on **computer A** and **make sure that all the mirrored files are closed** | ||
+ | - [[other:lsce_cloud#synchronizing_folders_with_owncloud|Install ownCloud and create a folder configuration]] on **computer B** | ||
+ | * e.g. LOCAL folder <wrap em>@ B</wrap>: ''<some_disk_different_from_c_on_B>:\Users\<your_login>_owncloud'' | ||
+ | * e.g. REMOTE: ''Backup/<your_login>_owncloud'' | ||
+ | - Watch content from **computer A** appear in the LOCAL folder on **computer B** ! | ||
+ | - Change some content on **computer B** and **make sure that all the mirrored files are closed** | ||
+ | - Go back to **computer A** and check the updated content (from **computer B**) | ||
+ | - You can also [[#checking_owncloud_activity|check the ownCloud activity log]] on both computers to make sure that things took place as expected | ||
+ | |||
+ | ==== Synchronization errors? ==== | ||
+ | |||
+ | There should not be any errors if you work cleanly (save a file on a computer before accessing it from another computer)! | ||
+ | If [[#checking_that_things_are_working_correctly|things don't seem to work correctly]], try to identify and solve errors as soon as possible! And try to recover files from the [[#space_management|Deleted files]], or older versions of the files. | ||
