I use "svnadmin hotcopy --incremental" command to create backup. Subversion
1.9.5. It was discovered that this command recreates already backuped
revisions files which size exceeds e.g. 120kb in directory db/revs/. Backup
log (1st backup was made to empty folder, next ones to the same folder):
C:\Users\Администратор.WIN-DBM2OE9OJ54>svnadmin hotcopy

D:\Repositories\Sandbox D:\Test --incremental
* Copied revision 14.
* Copied revision 21.
* Copied revision 22.

C:\Users\Администратор.WIN-DBM2OE9OJ54>svnadmin hotcopy
D:\Repositories\Sandbox D:\Test --incremental
* Copied revision 14.
* Copied revision 21.
* Copied revision 22./

And so on with each next hotcopy --incremental command. Binary comparison
revision 14, 21, 22 files of original repositary and backup gives equal
result. What reason of this strange behaviour?
