svn backup question
Hi,
I would like to use xcopy to directly backup a SVN repository,
is it ok? I am not quite concern about the last few commition.
I just hope the backup contain almost all the data of the
repository but not must fullly all.
And in the transaction directory, It seems there is data there
about fail transaction ? May I clear the failed transction data?
many thanks,
PanTao

This topic is covered in the subversion book.
http://svnbook.red-bean.com/
If you simply copy the files, and any svn transaction happens during the
copy, you're at risk of having a corrupt backup. If you disable all
access to the repository and copy the files, you should be fine.
The recommended backup method is to use hot-backup.py, which eliminates
these problems and produces a reliable backup every time.

For a one off, why not use
svnadmin hotcopy currentRepo backupRepo
(which is used by hot-backup.py as others suggested)

I see.I have use svnsync to make a up-to-date backup and would like to make
a copy to move disk at some time as additional backup.

I don't know what xcopy is, but you should be very concerned about
getting a complete and always up-to-date backup. It will be very
inconvenient for you if you ever find that you need to restore from
backup, but your backup is not completely up-to-date. There are many
backup strategies that will guarantee an up-to-date backup so you
should choose one of them.

Yes, with "svnadmin lstxns" and "svnadmin rmtxns"

For windows, I would recommend installing Python from
http://www.python.org/ftp/python/2.5.1/python-2.5.1.msi
and using this script in the distribution:
tools/backup/hot-backup.py
You'll get safe backups.
