A simple distributed backup system developed in java
Under de ./src directory run the following command to compile the code:
$ sh ../scripts/compile.sh
After compiling, go to the Build folder located in src folder. In that folder you can run the following commands:
Initialize the peer running the following command:
$ sh ../../scripts/peer.sh <version> <peer_id> <svc_access_point> <mc_addr> <mc_port> <mdb_addr> <mdb_port> <mdr_addr> <mdr_port>
To run the TestApp you should run the command:
$ sh ../../scripts/test.sh <peer_ap> BACKUP|RESTORE|DELETE|RECLAIM|STATE [<opnd_1> [<optnd_2]]
To cleanup the files run the following code on Build folder
$ sh ../../scripts/cleanup.sh <Peer_Id>
The aim of this project is to elaborate a distributed system service for backing up files in a LAN.
All the features requested for this work were implemented:
- Chunk backup
- Chunk restore
- Delete a file
- Manage a local service storage
- Retrieve local service state information
We also implemented the following enhancements:
- Backup Enhancement - Each chunk is not stored more times than its replication degree;
- Restore Enhancement - Using TCP Protocol;
- Delete Enhancement - Upon a delete command, peers that are not working by the time of the request will receive the delete command when connected.
