ECIP "Erasure Code Internet Protocol" Developed in 1996, was the first use of FEC "Forward Error correction" on the Internet.

Coding for Distributed Storage wiki for regenerating codes and rebuilding erasure codes.

How it compares to the near optimal codes mentioned above is unknown. It also successfully exploits the large register size of modern CPUs. An erasure coding topology provides all the information the replication service and geo-distributed erasure coding service need to implement erasure-coded protection. Many parameters can be set, like the size of the width of the band and size of the finite field.

Feclib is a near optimal extension to Luigi Rizzo's work that uses band matrices.

Software FEC in computer communications by Luigi Rizzo describes optimal erasure correction codes.

Jerasure is a Free Software library implementing Reed-Solomon and Cauchy erasure code techniques with SIMD optimisations.

"Network Coding for Distributed Storage Systems". Brighten Wu, Yunnan Wainwright, Martin J. Each shard is 1/K the size of the source data (1 K N). Our S3 compatible cloud storage means you can store your data, in the cloud, affordably with South Africa's trusted online storage provider.Parity check is the special case where n = k + 1. What Is Erasure Coding An N, K erasure code encodes source data into N shards (N 1).

You now know how to backup your Windows machine to Z1 Storage cloud storage. Our backups at Z1Storage allow up to 1Gbit upload per storage pod as of 2021.Īlternatively you can setup scheduling by clicking on the Schedule Navigation button

Note: The internet connection used during this tutorial was only 20Mbit, so we see it reaching the lines full capacity. If you would like to run the backup immediately, select the play button. _info) Selecting the **Send report after completion** will make it easier for you to keep track of the backup success._ Hence we suggest only modifying this if you find performance is below normal throughput. Going beyond an optimal number can degrade the performance. _info) More threads will initiate more simultaneous uploads. Good, now we see the backup is setup, you will also see and option on this screen to include/exclude files, and how many threads to use, we suggest leaving it on the default 4 threads. For this tutorial, we just made it "Duplicacy" Storage: Select a Bucket where you would like to backup to.īackup ID: This needs to be filled in, you can select an ID of your choice for this backup. Now, we setup the backup on this pop-over screenĭirectory: Next to Directory, click on the Green icon And browse to the local directory or file you would like to back up. Select Backup on the navigation, then click on the small plus sign, top right.

(please remember to keep this password safe as you will need to reuse it at a later stage) In the next section, we can configure encryption, erasure coding etc.įor this tutorial we will just set a name and the password Or leave it blank if you wish to store the data in the root of the bucket. You may select a directory within the bucket, You will see the bucket name appear in the config page:

Once your bucket has been selected, Click on Select: In our tutorial we'll use the z1storagetutorial bucket we created beforehand. Service Provider: We will select Amazon (or compatible)Īccess ID and the Access Key: Then we have the Access ID and the Access Key, these you will need to get from the Z1 Storage client area under the Integrations tab.Ī new pop-over will appear, here you need to select the bucket you would like to use. As Z1 Storage is S3 API compliant, we will use this connection method to access your bucket, data and files within the our cloud storage. You will see a pop-over appear, it will look like this: Within the left-hand side navigation, select Storage: Now it's time to setup Duplicacy to use your Cloud storage with Z1 Storage: Setting up S3 compatible storage on Duplicacy Your dashboard will look something like this: This will open your browser and take you to the control panel: on This will run Duplicacy in the background and it will also create an icon within the " hidden icons" section in windows You can download it from their website: here In this tutorial we'll be downloading, installing and configuring the Windows version of Duplicacy. Duplicacy backs up your files to many cloud storage providers, it includes client-side encryption and it offers the highest level of deduplication across platforms.
