Oops.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Standard Backup Strategy<\/strong><\/h2>\n\n\n\n<p>A <a href=\"https:\/\/www.techtarget.com\/searchdatabackup\/definition\/3-2-1-Backup-Strategy\">3, 2, 1 backup strategy<\/a> is the primary data, a local copy on different media, and one copy&nbsp; offsite.&nbsp; I only have my 1 onsite and my 1 cloud backup so I&#8217;m shy one local copy.&nbsp; Yes, I have RAID 1, but <a href=\"https:\/\/www.raidisnotabackup.com\/\">RAID is not a backup<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Now that I have realized my error, how do I do a local backup?<\/strong><\/h2>\n\n\n\n<h2 class=\"wp-block-heading\">Criteria<strong>:<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>I want a backup with the most critical data backed up and available to my computers, Mac and Linux.&nbsp; The backup will contain home videos, photos, financial documents, etc.&nbsp; I&#8217;d like to take a snapshot after every backup as well.<\/li>\n\n\n\n<li>I also want a Hyper Backup with snap shots, versioning etc. of the data I&#8217;m sending to the cloud,&nbsp; everything but my time machine backups for my Macs.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Budget<strong>:<\/strong><\/h2>\n\n\n\n<p>Big enough to meet my minimum requirements listed above, but not more. $200 &#8211; $300 was my thought.&nbsp; The ultimate would be a second Synology NAS to hold Hyper Backups with snapshots AND have the critical data easily accessible, but that is a bit out of my price range.&nbsp; My original thought was an 8 terabyte WD Black external USB on sale at Best Buy for $189, so that is the bottom end of what I will spend.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">My Solution:<\/h2>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Rsync of Data so I can Access It Directly<\/strong><\/h2>\n\n\n\n<p>For a backup of the system:&nbsp; <s>I&#8217;m doing a USB copy backup to an old 3 TB USB drive for a convenient backup of my most critical information.<\/s>&nbsp; <s>This allows an air gap to protect from Viruses and ransomware, but also the ability to read the files while I&#8217;m restoring from another local solution or my cloud hyper backup.&nbsp; I plug it in on Fridays after work and unplug it Sunday morning so backups can happen on the weekend and it is air gapped 6 out of 7 days. <\/s>I believe and agree with everything I just wrote.  My issue is  currently can&#8217;t get the USB drive connected directly to run at sustained rate higher than 3 &#8211; 5 mbps.&nbsp; More on that in my post on <a href=\"http:\/\/192.168.7.21:8000\/index.php\/2024\/05\/14\/synology-slow-backup-speeds-4-mb-s-usb-3-0\/\">backing up a Synology NAS up to a UBS 3.0 drive<\/a>. <\/p>\n\n\n\n<p>I&#8217;m moving to another option &#8211; Rsync to a Raspberry Pi with Open Media Vault &#8211; a single drive NAS. More details on that solution below.&nbsp; I don&#8217;t get the air gap, but it gets me an easily accessible copy of my data.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Local Hyper Backup<\/h2>\n\n\n\n<p>For my second local solution I want a full Hyper Backup of all my data.&nbsp; I&#8217;m going with another homemade Raspberry Pi Open Media Vault NAS with a single drive to hold the Hyper Backup.&nbsp;&nbsp; It will also provide me with one more benefit, more on that later on.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Building the Raspberry Pi NAS Devices<\/strong><\/h2>\n\n\n\n<p>For the homemade NAS devices I went with 2 raspberry pi 4 2 gb and Seagate Iron Wolf 8 tb drives.&nbsp; I have each hard drive in their own external enclosures hooked up through USB 3.0 to the Raspberry Pi in a rack.&nbsp; I put Open Media Vault on the Raspberry pi so I can easily do configuration and share via SMB, NFS and rsync.&nbsp; This makes two relatively cheap but effective NASes with reasonable protection.&nbsp;<\/p>\n\n\n\n<p>The Seagate Iron Wolf drives are $174 a drive and $20 for the enclosures, so $400, I already own the Pies.&nbsp; This puts me a little more than twice a single consumer grade drive, but with twice the protection with two copies.&nbsp; I went with the Iron Wolf drives because they are on Synology&#8217;s compatibility list.&nbsp; When I can afford to buy a diskless Synology device, I already have the drives (or some of them if I go for a 4-bay) for my second Synology NAS.<\/p>\n\n\n\n<p>Also went one step further.&nbsp; Rather than using the EX4 file system, I am using Open Media Vaults enriched BTRFS support on the Rsync backup.&nbsp; This allows me to implement snapshots of my NAS for the backup I can access.&nbsp; Yet a little more protection and some versioning.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>In the end I went for what I think is a solid solution that meets my needs. 1. A readily available backup of my most precious information. 2. A solid onsite back up solution for that data and everything else, with an upgrade path to another Synology NAS for a full local backup solution.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<p>This article has a nice overview of all options, and a good grid of what equipment goes with which backup solution.&nbsp; There are supporting documents with instructions for each of the available options.<br><a href=\"https:\/\/kb.synology.com\/en-my\/DSM\/tutorial\/How_to_back_up_your_Synology_NAS\">https:\/\/kb.synology.com\/en-my\/DSM\/tutorial\/How_to_back_up_your_Synology_NAS<\/a><\/p>\n\n\n\n<p>Thanks to Space Rex and his walkthrough of the backup options for Synology Products:<br><a href=\"https:\/\/www.youtube.com\/watch?v=f6AyeeLxzN8\">All Synology Backup Methods Explained and Which One is Right For You?<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/pimylifeup.com\/raspberry-pi-openmediavault\/\">Installing OpenMediaVault to a Raspberry Pi<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>May 14th, 2024 Situation: I&#8217;ve been running my Synology with a remote backup for a couple of years.&nbsp; I love the Synology NAS and their cloud backup solution.&nbsp; I&#8217;m using Synology&#8217;s Hyper Backup pushing my data to the Synology&#8217;s S2 cloud.&nbsp;&nbsp; I also have local snapshots turned on,&nbsp; but no local backup on a separate&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[8,7],"tags":[],"class_list":["post-194","post","type-post","status-publish","format-standard","hentry","category-general-it","category-raspberry-pi"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.8.1 -
