2100 accounts is not too

2100 accounts is not too much, but maybe if they have very large rosters, or big vcards (with uncompressed images as avatars...)
In WebAdmin -> Nodes -> your node -> Database... you can view the Mnesia tables, the amount of elements and table size. Check if any of them looks suspicious to be abnormally big.

Otherwise, maybe backup/dump is not good enough to backup such a database. In that case, you can do a dirty backup: simply copy the mnesia spool dir, preferably when there is little activity in the server (at midnight).
