Inconsistent delete behavior between cp and rsync

[ViRb3]

rsync will delete any files from $HDD_LOG that are no longer found in $RAM_LOG:

rsync -aXv --inplace --no-whole-file --delete-after "$RAM_LOG"/ "$HDD_LOG"/ 2>&1 | tee -a "$LOG2RAM_LOG"

While cp will simply merge them:

cp -rfup "$RAM_LOG"/ -T "$HDD_LOG"/ 2>&1 | tee -a "$LOG2RAM_LOG"

I'm not sure which behavior makes more sense, but it should definitely match between the two cases. I personally think merging is more useful since then I can configure my journald to only keep 50MB of logs, so it will delete old logs, but if log2ram already saved them to disk, they should not be overwritten.

The rsync is the best here. The goal of log2ram is to copy from RAM to Disk.
cp command is here for fallback purpose.
