logfile grows after using svnadmin hotcopy

Hi, folks.

We're running svn 1.1.3, and while examining my nightly respository backup scripts, I noticed that the repository's size increases after a backup with "svnadmin hotcopy", even if no commits have occurred since the previous backup.

On closer inspection, it appears only a logfile is increasing; in this case "log.0000000016" is what's growing.

I sniffed around the FAQ and list archives, and came across a few hints that this is normal, but nothing so far that actually explains what this logfile is for. It's hinted that this file will disappear automatically after a while, but it's not clear to me what causes this to occur.

The FAQ states "If you keep all the logfiles around forever, then in theory Berkeley DB can replay every change to your repository from the day it was born. But in practice, if you're making backups, it's probably not worth the cost in disk space."

The way this is worded, it seems to imply that, once the log file is removed, some ability to recover old commits will be lost, but it's written ambiguously, so I don't get it.

Can anyone elaborate? Thanks very much (in advance)!

Regards,
Owen
