RE: Synology: minimserver scans #snapshot btrfs subdirectory One suggestion also if I may : when deleting a file on a synology, if the bin option is activated, the files goes to a #recycle directory at the root of the music files with the same path as the original one. 以 Synology DS216+II 為例,這是一台擁有 2 個硬碟插槽的 NAS,除了最基本使用 RAID 避免單顆硬碟失效造成資料損毀之外,接下來就讓 Mowd 好好介紹如何利用 NAS 內建的功能來保護資料吧! 備份良方:Samba + Snapshot Replication (Btrfs 快照功能)一、設定步驟 1. The Btrfs file system and the non-encrypted shared folder were used in the above tests. This is the model with more ram pre-installed, and has an expansion slot for a 10g card (which I used, but is not included at this price) or an M. Hos oss har du alltid en och samma konsult. Btrfs was designed to address obstacles often encountered in enterprise storage systems, such as fault tolerance, management, and data protection. I looked at rsync from the PCs, although there are so many warnings and caveats that it doesn't come across like a reliable solution. this doubles the music files up to 256 times (the max number of snapshot folders). I'd use btrfs and would keep backing up like you are planning. Local snapshots of shared folders on Btrfs file system and advanced file LUNs; Schedule snapshot and customize retention rules; Remove or lock versions; Browse and restore snapshots in the #snapshot folder in all file services or File Station; View snapshot data in the Previous Versions tab in the Properties dialogue on Windows PC. And not supported on small NASes. In addition, Synology's LUN Snapshot lets you create up 256 snapshots per LUN using point-in-time technology without having any impact on system performance. By leveraging the availability of Btrfs file system to more models, the Synology NAS includes state-of-the-art data snapshot technology, allowing for flexible point-in-time recovery of files, while only using a fraction of the storage space and computing resource compared to traditional backup. 4GB DDR3L-1866 memory, expandable up to 8GB; Scalable up to 9 drives with Synology DX517 / Quad-core processor with AES-NI hardware encryption engine; Dual 1GbE LAN with failover and Link Aggregation support / Encrypted sequential throughput at over 225 MB/s reading and 221 MB/s writing / Advanced file system offering 65,000 system-wide snapshots and 1,024 snapshots per shared folder / Dual-channel H.

We have two Synology RS815RP+ devices set up with High Availability. The RS3617xs is also powered by a comprehensive Btrfs file system with snapshot technology. A benchmark report from Phoronix, a leading technology website for Linux hardware reviews, showed similar result. I'll make some snapshots with the built-in command. 1 Cloning Virtual Machine Images and Linux Containers 4. " Btrfs also has "a number of the same design ideas that reiser3/4 had". It could cause performance issues for sure (not Btrfs, but snapshots in general require IOPS). Free & Open Source unified file and block storage, VM, and Docker system with templates, a self-healing file system, snapshots, and replication. For example when I'm restoring a vzdumped. Automatic File Self-Healing Detects and recovers corrupted files without user intervention. The port count is still the same and comprises a quartet of embedded Gigabit, dual USB 3 and a high-speed Infiniband port for connecting the RX1217 disk shelf. With BTRFS there are various volume maintenance that can be done e.
