I am currently running a Synology NAS. What happens when I lose power while the NAS is writing to the disk? Is BTRFS robust enough to recover from power loss while in use?

I’m deciding whether to buy a UPS. Would prefer not to buy one. I will have backups so in the event of data loss, the only annoyance would be to restore from them. I will not be writing to the NAS often, and most of the time it will only be for scheduled maintenance (snapshots, clearing recycle bin, data scrubbing, etc.). I don’t mind losing the written file since most of the writes will be copying from SD cards or exporting from RAW files

Edit: I’m using SHR with 1 drive redundancy
