An external USB drive that I use solely for full and incremental backups is developing bad blocks. For pricing reasons, I'm going with a new drive which uses SMR for recording. I backup with rsync and a hard link tree for incrementals which means that file data is typically not overwritten at the file level. Metadata of old files changes when a hard link in a new incremental is made to the preexisting file. Are there any things I should watch out for this use case? Particular filesystems that are either good or bad for SMR drives? I obviously want the system to be reliable, but I doubt that making the system rewrite shingles over and over again due to frequent updates to the same disk blocks is good for the longevity of the drive. Any info/opinions appreciated.
