I have about 500GB of data (photos, documents, videos etc.) that I have accumulated over the years. Currently, I keep them on my computer and rsync all additions / changes once a month or so to an external hard drive. Do I need to be worried about data loss (sectors going bad, bit rot, bit flip, whatever it is called)?
To clarify,
-
None of this is commercially important; I just don’t want to get into a situation where I look up an old family photo or video twenty years down the line and it has got corrupted.

Both my computer and the external HD are HDDs. They are fairly cheap here (and very cheap if second hand). Buying SSDs or dedicated hardware would be expensive.
6$ is about 500 rupees. I can get another HDD for double that price.
I do copy some important files to Google Drive, but I don’t pay for it, and I don’t rely on it.
If you don’t pay for it, you can’t rely on it
Right, which is why I prefer to rely on local backups. Much cheaper in the long run.
I used to work with a guy who was religious about backing up his files to an external drives. Until someone broke into his house and stole his computer AND his external drives. He lost everything.
