Fixed Content Aware Storage (FCAS) system includes a file system configured to store the Fixed Content data and a database system configured to manage the stored Fixed Content and its metadata along with other related information. Additionally, the FCAS includes data integrity resolving means. The data integrity resolving means executes a file system recovery procedure and a database recovery procedure. The two recovery procedures are executed separately, whereupon the data integrity resolving means compares the corresponding lists of entries in both the file system and the database from viewpoint of pointers. Subsequently, the data integrity resolving means selects and recovers only entries having the complete file and metadata pointers and extracts and stores all pointer-incomplete entries, files and metadata, in temporary memory area. The inventive FCAS also contains a recovery point extracting means, which, upon a request from the archive software, extracts and returns to the archiving software a recovery point as well as other recovery-related information.
