[[!tag obnam-wishlist]]

Could Obnam keep a local cache of remote repository metadata, like Duplicity does?  I was looking through an Obnam log and noticed how many remote file accesses it does for each file it backs up.  If it cached that data locally, it could do it much faster.  The last-modified time of the repository could be stored in the remote repo, and if it matches the local cache, a lot of time could be saved.

That is indeed a good idea. Unfortunately, the correctness of caches is often tricky, so I've been putting off implementing this until more important things work first. Also, not caching metadata forces me to do other things to make Obnam fast. But I'd like to do the caching too, some day. --liw

[[done]] duplicate, and also an old wishlist bug. Keeping this open
isn't making this happen. --liw
