High-Seas

With High-Seas, a second Seafile service is available alongside Project-Seafile at the Projektablage, with which files can be exchanged and stored in the cloud. Unlike Project-Seafile, the High-Seas quota is not tied to the quota of the respective project at the Projektablage, but can be selected independently of this and can be several TB. In contrast to the other sub-services of the project repository, using High-Seas comes with a fee.

General information

How can the service be requested?

We recommend a consulting us before using High-Seas for the first time. Please contact the LUIS support team for this. If you decide to use High-Seas, the next steps can also be initiated in this way.
What are the costs?

Due to the comparatively large amounts of data that can be stored in High Seas, a fee is charged for this service. This is based solely on the hardware costs for providing the server resources required for storage. In particular, neither personnel costs nor license fees are included. The price is mainly based on the amount of memory used, but also partly takes into account the quota set:

(Used memory in TB - 90% + Quota in TB - 10%) - 105€ per year

This value is determined daily and averaged over the billing period of one year. The two-week maxima are used for the values of the occupied storage and the reserved quota.

Invoicing takes place annually in the middle of the year.
How much storage space is available?

The available storage space (the quota) can be selected independently of the quota of the respective project space at the Projektablage and can amount to several TB (terabytes). Please note that the LUIS must be contacted in good time for quotas of 5TB or more, as preparations may be necessary.

To change the quota, please send an e-mail to LUIS support.
How can the service be cancelled?

If you no longer wish to use High-Seas in a project space, please delete all data for this project from High-Seas and deactivate the service in the administration interface. Then please send an email to the LUIS support team to have the quota set to zero. Usage will then continue until the end of the current billing period, but - since no memory is used and the reserved quota is zero - no more costs will be generated. Please note that such a change will only take effect after a delay of two weeks (see ‘What are the costs?’).

Notes

Sepcial features of High-Seas in comparsion to Project-Seafile
As the transfer of potentially large amounts of data to and from High-Seas can place a significant load on the university's network for a longer period of time, the overall connection to the service is throttled to 1 Gbit/s. This available transfer rate is shared evenly between all users.

Due to the large amounts of data, there is no backup for High Seas, in contrast to Project-Seafile. However, the data is stored on redundant hardware. In addition, like with Project-Seafile, High-Seas features a the versioning, covering a period of 90 days.

Frequently asked questions for High-Seas

The Desktop Syncing Client fails to synchronise. How can I fix this?
In rare cases, the sync client may enter a state in which synchronisation fails.

In this situation, you should first ensure that you are using the latest version of the Desktop Syncing Client. The latest version can be downloaded from the manufacturer's download page. As newer versions usually fix bugs, the problem may already be solved after the update.

If the error still persists after the update, you can try the following steps:

Please back up all modified files that have not yet been synchronised to a separate folder on your local computer.

Initiate a manual synchronisation. To do this, right-click on the relevant library in the client and select the sub-item ‘Synchronise manually’.

If the problem persists: Initiate a new synchronisation by right-clicking and selecting ‘Resynchronise’.

If the problem persists: Uninstall the sync client. During the uninstallation process, please answer the question ‘Do you really want to remove the account information for Seafile’ with ‘Yes’. Then reinstall the sync client in the latest version and set up your account again. You can find help on setting up your account in the articles on Cloud Seafile, Project-Seafile and High-Seas.

If the problem still persists, please report it to the LUIS support by e-mail. Please describe as precisely as possible how the problem manifests itself and since when it has been occurring. Please also send the log files of your client. In MS-Windows, these can be found by right-clicking on the client icon in the taskbar and then selecting ‘Log folder’. An Explorer window should open in which you can see the log files (‘seafile.log’ and ‘applet.log’).
The Desktop Drive Client fails to synchronise. How can I fix this?
In rare cases, the Desktop Drive Client may enter a state in which synchronisation fails, as a result of which changes are not transferred.

In this situation, you should first ensure that you are using the latest version of the Desktop Drive Client. The latest version can be downloaded from the manufacturer's download page. As newer versions usually fix bugs, the problem may already be solved after the update.

If the error still persists after the update, you can try the following steps:

Please back up all modified files that have not yet been synchronised to a separate folder on your local computer.

Initiate a new synchronisation. To do this, right-click on the Desktop Drive Client's icon in the taskbar. Under ‘Accounts’, navigate to your account and select ‘Resynchronise’.

If the problem persists: Uninstall the Desktop Drive Client. During the uninstallation process, please answer the question ‘Do you want to delete the SeaDrive account information?’ with ‘Yes’. Then reinstall the Desktop Drive Client in the latest version and set up your account again. You can find help on setting up your account in the articles on Cloud-Seafile, Project-Seafile and High-Seas.

If the problem persists, please report it to LUIS support by e-mail. Please describe as precisely as possible how the problem manifests itself and since when it has been occurring. Please also send the Desktop Drive Client's log files. In MS-Windows, these can be found by right-clicking on the Desktop Drive Client icon in the taskbar and then selecting ‘Log folder’. An Explorer window should open in which you can see the log files (‘events.log’, ‘seadrive.log’ and ‘seadrive-gui.log’).
The webinterface of Seafile shows the warning: „The number of metadata records exceeds the limit of 100000 files“. What does that mean?

This notification refers exclusively to the metadata feature introduced in version 13 of Seafile. Within the Seafile web interface, users can assign arbitrary metadata to files under “Views” and display them in various views. Currently, this functionality is limited to the first 100,000 files in a library, i.e., files added after this limit has been reached cannot be assigned metadata.

All other Seafile functions remain unaffected. In particular, there continues to be no limitation on the number of files in Seafile.
