![]() I would appreciate if someone could help clarify. I would think this alone would make the copy no longer compatible. If you have configured redundancy factor 2, two data copies are maintained. ![]() The capacity savings of erasure coding is in addition to deduplication and compression savings. Instead of replicating data, erasure coding uses a parity information to rebuild data in the event of a disk failure. Read more about Filebase’s erasure coding. Enabling erasure coding is not necessary, as Filebase already uses erasure coding for all data stored in Filebase buckets. Learn how to configure Duplicacy for use with Filebase. Wanted to backup to an external 12TB usb drive. Erasure coding increases the usable capacity on a cluster. Learn how to configure Duplicacy for use with Filebase. What is Erasure Coding Erasure coding increases the usable capacity on a cluster. Just bought a ds920+ and plan to run 4x 4TB HDD in SHR with btrfs, i.e. It seems like copying a Erasure Coding enabled storage to another storage without Erasure Coding also takes up the additional space the feature requires (40% more for 5:2). You can run duplicacy either natively or in the container. If I performed the COPY to B2 now (without Erasure Coding) and then I eventually I move the local storage to one with Erasure Coding), would the COPY from local to B2 still be compatible? Would I need to re-upload everything to B2 all over again? My intention is to keep the cloud set with a longer retention so the prune will be more aggressive on the cloud storage. Obviously copying a 10TB storage to the cloud will take a long time. An erasure coding topology provides all the information the replication service and geo-distributed erasure coding service need to implement erasure-coded protection. However, I want to push this backup to the cloud (B2) now since I feel uncomfortable not having a offsite copy. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored. The main goal of Borg is to provide an efficient and secure way to back up data. Optionally, it supports compression and authenticated encryption. Data deduplication represents an original set of symbols in a smaller set of code symbols while erasure coding. I eventually want to copy the backup (via COPY) to a new storage with Erasure Coding enabled but I can’t really do that until a few months later due to various reasons. BorgBackup (short: Borg) is a deduplicating backup program. Data deduplication removes redundancy while erasure coding adds redundancy. ![]() So I have a backup (10TB) to a local storage but I had this done before I learned of Erasure Coding. ![]() Also include hints and tips for less technical readers.Noob here and I have searched through the forum for the appropriate answer but to no avail. We welcome posts that include suggestions for good self-hosted alternatives to popular online services, how they are better, or how they give back control of your data. Service: Blogger - Alternative: WordPress Service: Google Reader - Alternative: Tiny Tiny RSS Service: Dropbox - Alternative: Nextcloud For EC policy RS (6,3), this means a minimum of 9 DataNodes. Erasure coding requires a minimum of as many DataNodes in the cluster as the configured EC stripe width. Encoding and decoding work consumes additional CPU on both HDFS clients and DataNodes. While you're here, please Read This FirstĪ place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control. Erasure coding places additional demands on the cluster in terms of CPU and network. ![]()
