Here is the scenario:
A user select some files using a browser or an app and send them to a server.
The server save them on the file system permanently.
The server save the address of the files on a database.
How can I make sure this scenario happens like a transaction? For example, do I need to calculate the number/checksum of files both at the client side and the server side? What happens if the server shutdown after the 2nd step and before the 3rd step? What other things should I consider for a robust file uploading?

Currently we are subscribed to GoDaddy for their dedicated server lease, and now we are considering just purchasing our own server and just moving off of GoDaddy.
I have no idea how to put all of my source code from one server to another and also move the database and other files. Please explain what process has to be followed for this.
Also wanted to ask if their would be any changed for the third party tools i have used in my application?
To migrate my web application from one server to another I would do following :
Make a list of all transferable which would be:
Latest and running Source code on the server (ideally located in wwwroot)
database back up files (usually .mdb or .bak)
Copy source code and database back up to targeted server. Obviously depending upon type of the server you may need to set up the site in IIS and and point it to new directory
Restore database backup on database server
edit web.config to point to new database server and credentials.
Another important tip: If you have kept domain name with GoDaddy and only changing hosting server you may also need to change namedserver of you domain, without which you will not be able to point your domain to new hosting provider!
You may not succeed on the very first attempt of copying your stuffs to target server. It's always better to maintain back up so that you can copy files again and again in case something goes wrong on the new server.
As long as third party charges are concerned please check with your service providers they may be able to guide you best. For above simple stuff you do not need to worry about license stuff.
All the best!
I have cPanel access on two different servers and would like to transfer from one server to another. The original size of the account on the first server is close to 15GB.
Currently, the only two ways I can think of are:
Backup using cPanel then Restore on the second server. But this process times out. I get "Failed - Network error" error
Use FTP App like Filezilla to login and transfer files from that. I haven't tested this but I think it first downloads the files on my local machine (temp folder) then uploads them to the second server.
My problem with option 2 is that this means I will end up using 30GB of data transfer if it actually does that.
What is the best way to transfer from server to server using cPanel?
I have limited knowledge on this. I will suggest you some tips.
1.Backup using cPanel then Restore on the second server. But this process times out. I get "Failed - Network error" error
The backup creation is failed due to the high size of account. So that reason that way is not possible.
Use FTP App like Filezilla to login and transfer files from that. I haven't tested this but I think it first downloads the files on my local machine (temp folder) then uploads them to the second server.
You can download the whole content to your PC or download one folder by folder like first home, mail, and etc and upload to new cpanel account using ftp
Could you please open a support ticket to your hosting provider they will help you create from server backend using /script/pkgacct.
Thank you.
I have a remote server running SQL Server 9.0.3042, trying to subscribe to a publication on a server running SQL Server 10.0.2531.
These servers are on different domains which basically hate each other and largely refuse to allow their users access to each other.
They do both communicate nicely with a third domain, and it is a user from that domain which I am using as the process owner on both servers.
I have created a shared folder on the publishing server, and I am using it as the Snapshot folder, set via Publication Properties -> Snapshot -> "Put files in the following folder" and have confirmed that the files are being published locally and can be accessed via the shared folder.
The Snapshot Agent on the publishing server runs and appears to complete successfully.
I've then created a Pull subscription on the subscribing server and told it to run with the Agent Process Account of the same user that runs the snapshot agent on the publisher.
I've redirected the snapshot location to "Alternate folder" and set that folder to be the shared folder on the remote server that I set up earlier.
The Pulling server connects correctly to the Publishing server, And then fails because "The process could not read file "\[server].[domain][share][snapshot directory][file].pre" due to OS error 5"
I've logged into the Pull server as the executing account and manually navigated to, and opened, that file. I've done the same on the publishing server.
I'm out of ideas. What am I screwing up?
OS Error 5 is ERROR_ACCESS_DENIED. You're not being allowed to get to the folder. Check to make sure that the user account trying to get to the files has at least read access to the folder containing the files.
The decision has been taken that we're pretty much on the point where we're going to move every user in the company over to a brand new domain, and that this problem isn't worth the time and effort of fixing.
I did find this SO question which relates a similar problem, but I don't intend to investigate this matter any further.
Does anyone know of a script or program that can be used for backing up multiple websites?
Ideally, I would like the have it setup on a server where the backups will be stored.
I would like to be able to add the website login info, and it connects and creates a zip file or similar that it would then be sent back to the remote server to be saved as a backup etc...
But it would also need to be able to be set up as a cron so it backed up everyday at least?
I can find PC to Server backups that a similar, but no server to server remote backup scripts etc...
It would be heavily used, and needs to be a gui so the less techy can use it too?
Does anyone know of anything similar to what we need?
HTTP-Track website mirroring utility.
Wget and scripts
RSync and FTP login (or SFTP for security)
Git can be used for backup and has security features and networking ability.
7Zip can be called from the command line to create a zip file.
In any case you will need to implement either secure FTP (SSH secured) OR a password-secured upload form. If you feel clever you might use WebDAV.
Here's what I would do:
Put a backup generator script on each website (outputting a ZIP)
Protect its access with a .htpasswd file
On the backupserver, make a cron script download all the backups and store them
I would like to make a complete backup of my whole joomla 1.5 based site from time to time. How would this ideally be done? Are there any common pitfalls? Not that I only have ftp access to the hosting server. Is there a step by step tutorial somewhere? I am using latest Joomgallery and Kunena 1.0.9 (Legacy mode).
Maybe there is a good way to automate this?
There's two parts of the backup you have to worry about, the database and the files.
The first part is the database. It can be backed up using something like phpMyAdmin. If you don't have this available on your server already, it's not too hard to upload and get it going yourself. From there, you can just Export the entire database to a gzip file.
The second part is the code and uploaded files. The code base shouldn't change too often, so you could probably just make one backup of this. There's a number of ways. The simplest is to just download the entire folder via FTP, though if you're Linux, I'm sure someone will know a single command line to get all the changed files (rsync?).
The database is the main thing you have to worry about though: everything else should be able to be rebuilt just by reinstalling.
I think this: http://www.joomlapack.net/ is what you need. I use it myself and it works like a charm. Both for backups and for moving my Joomla installations from developer sites and to the real site.
get an FTP synchronisation tool and keep an up-to-date copy of your site locally. Then you could run the batch script
mysqldump -hhost -uuser -p%1 schema > C:\backup.sql
to create a backup of your mysql tables at various points in time.
edit
you would have to have MySQL Server installed on your local machine and path to its bin directory in you PATH, in order to run the mysqldump command without much hassle. -p%1 would take the command-line provided password, as you wouldn't want to store passwords in your batch script.
If you only have FTP access you are in a bit of a problem, as beside all files you'll also have to backup the database. Without accessing the database, a full-backup won't do you any good.
Whatever backup strategy you choose - be sure it can handle UTF-8 correctly. Joomla 1.5 stores all content with UTF-8, even when the database charset is set on 'iso-5589-1' - so when the backup solution is detecting the database charset, some characters like € or é will result in "strange" ¬ / é - not really what you'll want.
I absolutely endorse using Joomlapack - it works great. The optional remote tools allow you to initiate the backup from a Windows desktop machine - it performs the backup and downloads it. The remote has a scheduler, and you can also set it off to backup and download a list of sites.
Joomlapack also provides a file "kickstart.php" which you copy to your empty server account along with the backup, which automates the restore procedure. You do have to create an empty database with PHPMyAdmin or similar, and you are given the opportunity to supply the database parameters (host, database, username, password) during the process.
One pitfall I did run into with this though is that some common components can have absolute URLs in their configuration - e.g. SOBI2, Virtuemart. It's then just a matter of finding the appropriate configuration file, editing it and re-uploading it.
Another problem was one archive file (either ZIP or their JPA format) got a filename with a "?" character in it (from a Linux server) and this caused a bit of a problem trying to install it locally on a Windows WAMP stack - the extract process on the ZIP file failed, and it stopped the process completing cleanly.
I suggest using automatic backup service by http://www.everlive.net
Update:
Ok, here is some more information. EverLive.net is a website where you can create a free account. Enter your website details and you are ready to take your backups withe just one click. Restore is also possible in the same way.
Further you can use automatic backup option to take automatic backups at defined intervals. Other than that, you can use the website health check service to inform you if your website is not available.
