Hi, I am looking to centralise all of my files and media, with the highest protection.
I especially want to protect against “bit-rot” and other hardware errors that could cause silent corruption of my data files.
I am looking to use 2x6TB HDDs for my storage. I am comfortable with the command line and happy to poke around a bit.
If you choose Synology or Qnap, then bitrot is not something you need to worry about. The integrated function will go through the RAID and detect any bad block on the drives and auto-heal them. Especially Synology with BTRFS files system.
I hope this helps.
Here is what Synology says about BTRFS.
What are the benefits of Btrfs?
Implementing Btrfs volumes on Synology NAS delivers various benefits for enterprise users.
Metadata mirroring and increased data availability
Btrfs file self-healing
Snapshots and data protection
Low impact, big benefit
Taking a snapshot consumes only a small amount of additional storage space, while exerting little impact on system performance thanks to Btrfs’s copy-on-write architecture.
Frequent, scheduled backup
Automatically create point-in-time copies of data up to every 5 minutes without affecting performance, guaranteeing granular data backup and recovery.
Customizable retention policy
Retain up to 256 hourly, daily, or weekly recovery points according to your individual needs. Smart retention options automatically delete unneeded versions.
Capture snapshots instantly and backup data without worrying about files being modified or deleted during the backup process.
Employees can view earlier versions of files and restore them to a previous state by themselves using File Station or Windows File Explorer.
Instant SMB/AFP server-side copy
Compared with the traditional server-side copy, which requires processing time, Btrfs fast-clone technology allows instant file copy to be achieved on File Station, SMB and AFP protocols if the source and destination are both on the same Btrfs volume.
Additional benefits of Btrfs
Using the Btrfs file system on your Synology NAS brings a wide variety of benefits to DiskStation Manager and Synology packages.
Clone entire shared folders
With Btrfs, you can simply select a shared folder and make a clone of all the contents nearly instantaneously. This is useful when testing updates to websites or databases and you need a quick clone.
Frequently Asked Questions
Do I need to configure anything special to take advantage of the data integrity features of Btrfs?
The metadata mirroring and checksum features are enabled by default on all Btrfs volumes. For files, the copy-on-write and checksum features are enabled by default, but can be switched off for best performance.
How do I create a Btrfs volume?
Open Storage Manager and create a new volume. You will be prompted to choose a file system (btrfs or ext4) during the creation process.
Where can I create and restore file from snapshots?
Snapshot Replication (available on Synology NAS models that support Btrfs) includes options to take snapshots on demand or configure schedules and retention policies. You can browse and restore snapshots using Snapshot Replication, File Station, Windows File Explorer, or other file protocols.
How can I clone a shared folder on a Btrfs volume?
Open Control Panel and go to the Shared Folder tab. Then click the arrow on the create button and select Clone to clone a shared folder.
