I have two Synology NAS devices in my home lab that I’ve always struggled with being sure I have full backups of as they have grown pretty large over time. I have the 5 bay DS1512+ (with an additional 5 bay expansion), and I have a tiny 2 bay DS214SE. I didn’t plan my use of them this why but it just kind of evolved over time, such is how my lab is. Something breaks or is slow, I tweak to squeeze out better performance on a small budget and life goes on.
Currently I use the large array for normal file storage (music, photos, videos, ISOs, etc…), I used the extra expansion for transition storage over time when I moved stuff around (mainly VMs). I originally used the tiny 2bay NAS for my tiny portable lab based on NUCs. I now have the management components living on a iSCSI lun on there (VC, PSC, vCO, DNS, AD…) and for all compute I am now using VSAN across three white box machines (which is working fantastic!).
I’ve always struggled with backups in my lab. Any free options out there either won’t cover two VCs, cpu core limited or VM count limited. I’ve been using William Lam’s GhettoVCB forever, which is solid but mostly manual.
Enter….what I found this past weekend. Synology management software images that will work in a VM or baremetal! This is literally the same OS that runs on their devices. I first tried it in a VM to test it out. All seemed well except for updating as it appears to break so you have to wait for unoffical patches. To use this for real, I went ahead and swapped out the USB drive on my HP N40L which was previously running FreeNAS for backups.
This allowed me to setup a reoccurring RSync from the DS1512:
…And also allowed me to setup a reoccurring backup of the iSCSI LUN (holding the management VMs):
While the ~250gb iSCSI backup was pretty quick, the Rsync of 6 TB of small & large files is taking a while. Performance seems pretty decent, at least for my home lab that can be kind of…iffy given the amount of crazy crap I run on the large flat network of consumer level 1GB switches no tuning whatsoever.
Prior to this I was doing all my backups manually – both the rsyncs and ghettovcb backups. I would then a few times a year move a backup set outside of my house to a family member. I highly suggest you do the same! I do my best to follow the 3-2-1 rule, though I’m not doing great on the multiple types of media as my photo collection has grown too large to use “cloud” storage useful or economical.
Check it out for yourselves!
