backup / restore fails on large accounts

[mxcreep]

I had to migrate the accounts of two servers from another hosting company to mine and normally this is fairly easy using the admin backup transfer tool.

In this case I backupped both servers to my backup server and tried to restore all accounts on two servers in my network. Most of the accounts restored fine but some of them didn't. All of them were very large accounts >2GB and the restore ended in nothing, not even an error message.

I tried to gunzip / tar them manually and got a 'invalid compressed data--crc error' back from gunzip... After some googling it seems gunzip cannot handle files that large.

Is there anyone else having these problems and is there a solution for this ?
In my opinion DirectAdmin should be able to backup large accounts as well or at least warn you about the inability to backup these accounts. Now people are creating backups they might not be able to restore.

DirectAdmin has no idea if your kernel, or your filesystem, support files greater than 2GB; That was a linux/unix limitation for some time.

Try manually tarring the user(with zip and without) to see if any error is found on creation.

Then try manually untarring it (to a different location) on the same server to see if you get an error. If not, then try ftp-ing it to the new server and manually untarring it there.

Then at least you'll know where the error occurs; that'll make it easier to look for the reason it fails.

Tarring doesn't seem to be the problem, gzipping is...

I will try what you mentioned later, but since this is a 64bits box I'm not aware of any limits. Perhaps the boxes from the other host were not 64bits boxes...Can't check that anymore...

Guess I will have to check one of my own large backups if they unpack...

Anyway, thanks for the anwer !

I seem to recall a problem when gzipping on FreeBSD and then gunzipping on Linux. Or perhaps it was the other way around.

If you've switched from Linux to FreeBSD or vice-versa, then searching these forums might give you some idea if this is the problem.
