Wholly depends on how much stuff you’ve got. I’ve started having issues with the Linux io scheduler when the auto backups got large (1G+), the thing just hung and needed a power cycle.
Also what SD card you have, the durability between different models differ a lot. The SD card I use for my dashcam been working for years (A "SanDisk MAX ENDURANCE" card), some other cheaper SD cards can stop working properly after just months if you're using them for write-heavy stuff.
