RE: Taking mirror Backup of SVN Repos through 3rd Party Software

Hi Waseem,

We use the svnsync synchronize command with a fair amount of success. We have this set to run automatically in the hook scripts as described in the Red Bean Subversion book (available in html). This was successful enough that we chose not to use a third party tool to do the repo sync, (so I can’t really advise on 3rd party methods).

When that occasionally chokes we use svnadmin dump –incremental of a specific revision, and then svnadmin load to the backup server (mirror) location. It takes some modifying of the mirror repo’s /db contents to get the sync to run again after loading a revision to a synced mirror in this way.

My point being – simply – there are a couple other methods besides hotcopy – and these can be done incrementally which sounds more like what you’re already doing.

(Please excuse any leagal disclaimers that will follow – I’m not allowed to shut it off)

Hi Guys!

                  We are using 3rd party software that take (Copy/Paste) Backup of all databases of SVN on differential basis. I have some confusion.

 What's in all these *.txn folders (33740-q3q.txn, 1757-1d0.txn, 33753-q43.txn) Please guide ? Are they of any use? What is their importance for Us? Could they be ignored or excluded?

For some reason new set of files that are being dropped into these folders and they happen to be Alternate data streams, and which we do not seem to be able to pseudo mirror.
Thanks in

The only safe way to run a backup of a Subversion repository is to use the 'svnadmin hotcopy' functionality or equivalent functionality in other Subversion clients.
