I would only on occassion re-review these infrequently accessed content whether they qualify to be retained or whether to delete them (while at it, i'll also use dupeguru to check if i mistakenly kept multiple copies of contents by mistake, which can easily happen, and thus save on space). infrequently accessed or not, so these would never ever get ommited. were these folders located on the nas?įor my own backup i would backup shares on my nas i clearly knew should be backed up (i use hybrid backup sync that saves these jobs for share locations to be backedup). I'm unsure how you missed backing up folders that were least used. but now that you've put your backup to the test, now you see what you could have done better. also sorry this happened to you, i know you did your best with the backup, so kudos. Boot from the USB stick and configure as required.Disconnect all existing HDD from the PC and connect the NAS HDD.Find a PC with the required number of SATA ports greater or equal to the number of HDD in your raid 5 array.I used Rufus to create a bootable USB stick with persistent storage. For the OS, I used Ubuntu Desktop 20.04 LTS USB boot drive. Disclaimer: tested on the disks of a dead QNAP TS-451+ running QTS 4.5+, with a sane 4 HDD raid 5 array containing a Storage Pool with one volume. my past resume, which I only use when I am looking for a job but I would be angry if I would have to start from scratch, archive from past jobs, etc).

My backup strategy missed a few less used folders, the kind that you never access, but would hate to loose (e.g.

Today, I realise that I don't want to go through recreating the lossy files.

I decided not to backup lossy music files if I have the same file lossless.

However, when I defined my backup policy, two things I did not planned:

However I had to scan through countless threads to find a way to recover my data, but none with a complete procedure.īefore the usual RAID is not backup comments, let me say I do have backups.

What I could easily find is that it is dead, really dead. No status LED, flashing LAN, solid blue USB, various solid red or green HDD.
