| Live sync'ing software Has anyone found a reliable software product to sync 2 folders between 2 different servers over our WAN? I need something that will poll a particular folder and copy any changed files to another location. Thanks...

Double-Take? |
|
| reply to alightfoot
Sync Toy actually works really well but it doesn't do a live sync as files are updated over time. Works great manually though.

Double take is a great product and have used it for fail-over in the past, but unfortunately it is a little over kill for what I'm trying to accomplish here.

Thanks for the replies guys but I have a database on the inside that I need replicated to our colo 50 miles away. This database gets updated all day long during normal business hours and having live data in our colo is key. I've purchased some software like puresync that promise to do the job and never come thru or work for a few days and then need some kind of intervention. I was hoping someone here on the forum has something in place that works. I'm running Server 2008 x64 on the host server.

| How large of a file are we talking about? What about using Dropbox? |

DFS?
*Edit* Nevermind, didn't read that it's a database.
What type of database is it? |
|
| reply to devicemanage
The entire files total 30 gigs and is growing on a regular basis. They are all .mdb files ranging in size. Currently there isn't a file bigger than 65 mb but the majority are around the 5 mb size. Im testing with allway sync right now and it seems to be working - for today anyway.

Is it SQL?
maybe setup SQL replication
I wonder how a DB would act when some other software tries to copy its files, I know outlook will freak out if anything tries to sync an open PST file |
|
| its a mdb file, the copy does take place until the file is modified and by that point its closed. while the file is open it forms a .ldb extension which means the file is locked. Most sync'ing apps can filter those out and ignore them if needed.

kudos:3 | well if your looking for live sync then you'd need to beable to sync it while its open, in which case something ment for that DB type |
|
| well most sync programs need the file to be modified after the initial compare. So when it is open the file will not sync until it has been closed or updated.

kudos:3 | thats why theres special programs for dealing with such files, ie an Exchange DB is never going to be closed but still has to be backed up
there are ways but syncing only when the file is not being accessed is not the best |

The database is not our core operating database. Transactions come in from our clients to our main frame where a server is on standby waiting to read the transaction logs of the main frame. This server then takes the transaction information and updates the appropriate microsoft access database. This .mdb is never in use for more that a few seconds while it is being updated. Then, once updated, the file is stamped with its new date and time, the sync application is suppose to pole this directory for changes. Once detected, it will then copy the file to our colo to update our web server.
I hope this helps!

kudos:3 | wouldn't it be possible then to add some code so in the process of updating the MDB it saves it to 2 locations |
|
| reply to devicemanage
Yes that would be the best way, no doubt. But program doing the updating is already updating 2 locations, so to add one that is 50 miles away creates some lag and bombs out if the program. Hence the need for this sync app.

kudos:3 | maybe not have it do it directly but have the last part triger a file copy operation for the 50mile location |
|
| reply to devicemanage
thats where I'm trying to sync from, but I need the data to be live or at least 15 minutes old. The entire directory with all the mdb's is near 30 gigs and growing so I need the sync app which can archive all the files after the initial compare and only move the updated files. We are in the process of getting out 15 year old ds3 re-groomed, so we should have a few less hops up to the colo and speed things up. But for now the sync seems to be my only alternative.
