Merci à tous !

Now that Asker has given more context, I would lean towards the "storage of redundant data" interpretation. As Adrien mentions, a classic problem with Excel-based systems is that data would be entered and maintained by different users in different databases, or files. The same data is stored in several places, and that is redundant (in the sense of superfluous).
Of course, as Daryo is saying, no-one wants that: this is why it is undoubtedly counted as a drawback of that tool.

"redundant data" (data that is already recorded elsewhere under a different name) is data meant to be thrown away - one of the basic principles of building databases.

"redundant data storage" is about storing important/crucial data more than once by replicating it. As the same data is stored 2 or 3 or 4 times, only one copy is essential all other copies are redundant.

But no one in his right mind will go to the trouble of using "redundant data storage" (far more cumbersome and expensive than storing just one copy) in order to store data that is redundant.

Si l'on parle d'Excel, par exemple, il s'agit bien évidemment de gérer les doublons (les redondances).

Il s'agit d'une liste de systèmes informatiques avec une description de leurs avantages/inconvénients :

Apollo TXT: Incomplete IT system (e.g. missing interfaces to WWS for article selections) – not accepted for intended functions
MAS Excel: Most used tool to deal with functional lacks, redundant data storage.

Je n'ai malheureusement pas beaucoup plus de contexte. Merci à tous pour votre aide !

La question est plus que pertinente dans la mesure où, si les deux sont possibles, les deux ne signifient pas la même chose. Dans un cas, c'est le système qui est redondant (comme avec RAID) et dans l'autre ce sont les données qui sont redondantes (superflues, en double, etc. comme dans une base données). C'est ce que vous commentez qui dira ce dont il retourne. Si c'est bien de storage qu'il est question, je dirais stockage redondant de(s) données pour lever toute ambiguïté.

Without more of the ST, and a context limited to "Computers (general)", it is in my opinion impossible to decide how to read the phrase. Both interpretations ("redundant storage of data" and "storage of redundant data") are possible.

Examples of 1st interpretation:
- "A redundant data storage hardware can help decrease a system downtime by removing some of points of failure." (http://www.learn.geekinterview.com/data-warehouse/data-types... This is certainly not a piece of hardware dedicated to storing redundant data!
- "Redundant data storage at separate data centre" (http://www.1and1.co.uk/details-ftp-storage) Again, they're not building a data centre just for redundant data. They have redundant storage to make sure that data is available even when one data centre is offline.

Example of 2nd interpretation:
"The integration of such data in a single database object eliminates redundant data storage" (http://help.sap.de/saphelp_crm700_ehp02/helpdata/en/a0/9f0e4... All such data is in a single place, there is no need to store it twice.
