Home PC >> unraid NAS >> unraid NAS >> backblaze B2

[ninjanner]

Main use case is backing up 1.5TB of photos / family videos.

I am using syncthing to keep in sync the home PC to unraid.

Then from unraid I was going to run duplicacy to another destination with in unraid to store the backup. Then send to Backblaze B2.

Is the best way to do this , after the initial backup using duplicacy in unraid. Should my next option be scheduling the copy command to Backblaze B2?

Open to suggestions on best way of doing this.

After many questions in the forums and reddit and reading from others.

Here is the strategy that I set up.
My main use case / concerns is saving my digital photos that date back to 2003

My Backup Strategy Summary

1. Home PC to Unraid Storage:

   • Use SyncThing to sync files from your home PC to Unraid storage.

2. Unraid Storage Backup:

   • Use Duplicacy to back up files from the synced directory to another directory on Unraid.

3. Offsite Backup to Backblaze B2:

   • Use Duplicacy to copy the backup from Unraid storage to Backblaze B2.

Retention Policy

The retention policy in my Duplicacy setup is configured as follows:

1. Daily Snapshots: Retain all revisions for the first 365 days.
2. Weekly Snapshots: Keep one snapshot per week for snapshots older than 180 days but within the last 365 days.
3. Monthly Snapshots: Keep one snapshot per month for snapshots older than 365 days but within the last 365 days (effectively days 365 to 730).
4. Yearly Snapshots: Keep one snapshot per year indefinitely.

Backup Schedule

1. Hourly Backups: Run from 7:00 AM to midnight.
2. Daily Check Command:

   duplicacy check -a -chunks
   

3. Weekly/Bi-weekly Prune Command:

   duplicacy prune -keep 0:365 -keep 30:365 -keep 7:180 -keep 1:365 -a -exhaustive
   

This ensures comprehensive backup coverage and efficient storage management.

I am backing up around 1.5 TB of photos / videos.
