Claim 7:
8. A computer-implemented method, said computer-implemented method comprising:
obtaining, by one or more processing units, a plurality of transaction logs in blocks from a plurality of nodes of a data storage system, wherein said plurality of transaction logs include a first transaction log and a second transaction log;
for each of said plurality of transaction logs:
splitting, by said one or more processing units, said transaction log into log entries;
grouping, by said one or more processing units, said log entries into groups, said log entries in each of said groups being associated with a same data source; and
writing, by said one or more processing units, said log entries of said groups to empty blocks, wherein log entries from different groups do not share a same block;

identifying, by said one or more processing units, a same sequence of log entries from a written first transaction log and a written second transaction log; and
uploading, by said one or more processing units, one or more first blocks of said first transaction log that include said same sequence of log entries to an object-based storage, without uploading one or more second blocks of said second transaction log that include said same sequence of log entries to said object-based storage.
