I run Borg nightly, backing up the majority of the data on my boot disk, incl docker volumes and config + a few extra folders.

Each individual archive is around 550gb, but because of the de-duplication and compression it’s only ~800mb of new data each day taking around 3min to complete the backup.

Borgs de-duplication is honestly incredible. I keep 7 daily backups, 3 weekly, 11 monthly, then one for each year beyond that. The 21 historical backups I have right now RAW would be 10.98tb of data. After de-duplication and compression it only takes up 407.98gb on disk.

With that kind of space savings, I see no reason not to keep such frequent backups. Hell, the whole archive takes up less space than one copy of the original data.

@Sunny Backups are done weekly, using Restic (and with ‘–read-data-subset=9%’ to verify that the backup data is still valid).

But that’s also in addition to doing nightly Snapraid syncs for larger media, and Syncthing for photos & documents (which means I have copies on 2+ machines).

No backup for my media. Only redundacy.

For my nextcloud data, anytime i made major changes.

I tried Kopia but it was unstable and janky, so now it’s whenever I remember to manually run a bunch of rsync. I backup my desktop to cold storage on the first of the month, so I should get in the habit of backing up my server to the NAS then also.

Thanks for reminding me to validate.

Daily here also.

Daily backups. Currently using restic on my NixOS servers. To avoid data corruption, I make a zfs snapshot at 2am, and after that restic does a backup of my mutable data dirs both to my local Nas and CloudFlare r3. The Nas backup folder is synced to backblaze nightly as well for a more cold store.

Backups???

Using Kopia, backups are made multiple times per day to Google drive. Only changes are transferred.

Configurations are backed up once per week and manually, stored 4 weeks. Websites and NextCloud data is backed up every hour and stored for a year (although I’m doing this only 7 months now).

Kopia is magic, recommended!

rsync from ZFS to an off-site unraid every 24 hours 5 times a week. on the sixth day it does a checksum based rsync which obviously means more stress so only do it once a week. the seventh day is reserved for ZFS scrubbing every two weeks.

I honestly don’t have too much to back up, so I run one full backup job every Sunday for different directories I care about. They run a check on the directory and only back up any changes or new files. I don’t have the space to backup everything, so I only take the smaller stuff and most important. The backup software also allows live monitoring if I enable it, so some of my jobs I have that turned on since I didn’t see any reason not to. I reuse the NAS drives that report errors that I replace with new ones to save on money. So far, so good.

Backup software is Bvckup2, and reddit was a huge fan of it years ago, so I gave it a try. It was super cheap for a lifetime license at the time, and it’s super lightweight. Sorry, there is no Linux version.

Weekly full backup, nightly incremental

Backup all of my proxmox-LXCs/VMs to a proxmox backup server every night + sync these backups to another pbs in another town. A second proxmox backup every noon to my nas. (i know, 3-2-1 rule is not reached…)

Daily toward all my three locations:

• local on the server
• in-house but on a different device
• offsite

But not all three destinations backup the same amount of data due to storage limitations.

Depends on the system but weekly at least

Nextcloud data daily, same for the docker configs. Less important/rarely changing data once per week. Automatic sync to NAS and online storage. Irregular and manual sync to an external disk.

7 daily backups, 4 weekly backups, “infinite” monthly backups retained (until I clean them up by hand).
