Method and arrangements for node recovery

A method for node recovery of a first node (N1) in a system (103) comprising a distributed database (101), which method involves recovering at least one first database fragment (F1) in the first node;

• which method includes the step (114) of retrieving an old version of the first database fragment to the first node,
• characterized by the old version (120) of the first database fragment (F1) containing records (106) each marked with a first timestamp (108);
• the method further including the steps (115, 116, 117) of:
• making the old version (120) of the first databases fragment available to write transactions, which are requested in the system and which affect records (106) of the first database fragment;
• deleting records in the old version (120) of the first database fragment based on information from a delete log (110);
• scanning an up to date version (121) of the first database fragment in a second node (N2) for records with first timestamps (108) indicating a point in time later than or equal to a predetermined point in time;
• copying each record found in the scanning step to the old version (120) of the first database fragment.
