Abstract
A method, system for preserving access to deleted and/or overwritten documents for the retrieval in a system, wherein said document data is stored in a system filestore associated with a system database containing reference data to point to the document within the system filestore, the method comprising the steps of: determining that a delete/overwrite command has been issued; recording the reference data prior to or after deleting or updating of the reference data; inserting the recorded reference data in a set of access-preservation tables; and providing the set of access-preservation tables to hold the combined and separated reference data, which points to the deleted and overwritten documents within the filestore.
Claims19
A improved method for preserving access to deleted and overwritten documents within a system, to allow their identification, separation and manual recovery in case the document or document data was deleted or overwritten in error, wherein said document is stored in a system filestore associated with a system database or store that contains reference data to point to the document data within the system filestore, the method comprising the steps of:
- determining that a delete or overwrite command has been issued;
- recording the reference data prior to or after the deleting or updating of the reference data;
- inserting the recorded reference data into a newly added set of access preservation store or tables;
- and
- combining and separating deleted and overwritten data by means of automatically run procedure(s) to combine all other salient reference data connected with the reference data before system reference and documents are cleaned;
- and
- providing at least one but preferably two access-preservation/combination tables the first to point to the deleted documents, and version of;
- and
- second to point to overwritten documents and versions of within the filestore.
A system for preserving access to deleted or overwritten document data, from a document management system with the intention of archiving to storage media or to another document management system comprising:
- a database for storing reference information and supplementary document information;
- at least one trigger for catching and recording reference data that has been deleted and/or updated from the database;
- at least one access preservation table for storing access preservation data, the access preservation data being operable to point to the data that has been deleted and/or updated;
- and
- at least one stored procedure to combine data captured in the at least one access preservation/combination table.
A system for preserving access to deleted or overwritten document data, from a document management system with the intention of retrieval of a lost document to any storage media or to another another document management system comprising:
- a database for storing reference information and supplementary document information;
- at least one trigger for catching and recording reference data that has been deleted and/or updated from the database;
- at least one access preservation table for storing access preservation data, the access preservation data being operable to point to the data that has been deleted and/or updated;
- and
- at least one stored procedure to combine data captured in the at least one access preservation/combination table.
