March 11, 20251 yr Hi Guys, writing to ask some help troubleshooting my actual configuration and seeking advice on how to optimize what I already have. UnRaid: low power build based on J4105 8Gb Ram [actually this limit me to 6sata connected hd, I could add another 2 but I would be limited by PCI1x bandwith], just storage + some dockers 14Tb(Parity) + 14Tb + 8Tb + 4Tb + 4Tb EXt4 [tot 30Tb Free around 10Tb] + 500Gb cache BTRSF Cold storage for media/PMS Semi-working storage for lightroom pictures (meaning I use it to gain parity protection of my data, but it's quite slow...) Nextcloud in docker (as easily accessible cloud, and as destination target for an offsite Synology backup via WebDAV interface) PRO UnRaid (most important to me) If 1 hd dies, I've parity. If another dies, I can read data on the remaining, if no catastrophic loss of server, it's unlikely to lose ALL data at once Very optimized for low power consumption (everything is on cache and disks spindown easily) CONS low performance when writing to array, and important folders like picture skip cache bacause cache itself is not actually redundant Synology Ds415+ 18Tb BTRFS - no parity protection I use this to Rsync my file fron Unraid as a 2nd copy of my data I use HyperBackup over the www to backup offsite to another synology [previously tried to do directly from UnRaid via Duplicati but have had bad experice... Hyperbackup is so much easier] PRO so much more user friendly backup application both for local & remote backup better performance CONS not optimized for low power consumption Next Steps / Options: [Option 1] Unraid - keep as working machine 1° Create ZFS RaidZ1 with 3x8Tb for picture, to gain faster working speed at price of power consumption [I need to buy 8Tb, I've already one spare] 2° Keep 1 14Tb hdd not parity protected for MEDIA like movies and so on 3° Create a ZFS mirror for cache by adding a 2nd SSD thus gaining redundancy on cache (and using it also for picture) [1 need to buy a second SSD] Synology - keep as a local backup and use as starting point for remote backup 18Tb for backing Up Picture and personal doc 14Tb for backing Up Movies and so on PRO more performance? gain ZFS healing capacity for my personal files? CONS Convoluted workflow as now (rsync to synology and use synology for snapshots / offsite backup) worse powersaving performances [Option 2] Synology - keep as working machine Move all my personal filers to Synology and work from there [18Tb no parity] Backup Synology to Unraid, losing redundancy on the "working machine" [but having redundancy on the backup destination] Unraid - PMS and cold backup keep actual configuration and use it as a storage & plex media server PRO straightforward workflow (snapshot on working machine, backup software on woring machine ...) CONS need to keep Unraid for PMS, Unraid will be under-loaded working machine will lose redundancy Any suggestion and criticism will be very appreciated. I'm really in a rabbit hole and can't decide, time is a big constrain so I'd like to decide now and don't change workflow for many year to come
