Backup Running Very Slow

I have a problem here and I'm not sure where the source is.

When I initiate a Backup in DA, I see a file recorded in the Backup Folder which has UID = root and GID = root.
At some point I may get an email (~50% of times) advising Error creating Backup.
Tracking back on the LINK in those emails I find Error messages such as:

Error connecting to MySQL: Lost connection to MySQL server at 'sending authentication information', system error: 32

Error Compressing the backup file backup-May-23-2010-6.tar.gz : /bin/tar: backup/wenublog.com/email/data/imap/guran/mail/INBOX.Trash: File shrank by 5804308 bytes; padding with zeros
/bin/tar: Error exit delayed from previous errors

I can accept "previous errors" as a factor there, as I was Deactivating Plugins to test the impact on the Backup facility. (multiple successive backup attempts)

In the event, overnight I began to get emails (I was personally away while my FTP was Downloading 3 previous Backups dated from before this problem) advising me my Backups were complete.
When I opened DA and looked in Backups, all the 'root' entries had become normal 'user' UID/GID entries.

Latest Plugins have been: Extreme SEO; SI CAPTCHA and TweetMeme. Each of these, particularly the 1st & 2nd, might be 'compounding' data throughput in the Blog. It occurred to me that was a problem - is why I deactivated Plugins.

Am I missing something basic here? The reference to MySQL seemed to indicate a file corruption somewhere but as I say, when I got up this morning several Backup Report emails had come in.

Frankly, I don't trust those backups.
Just now, I initiated another Backup and currently have another 'root' file in the Backup folder, which I suppose will - very eventually, perhaps hours - become a backup.

Also my Bandwidth, indicated in DA, has doubled.

Thoughts please as I am not even skating on ice.

Thanks

I have done a Support Ticket - and of course, by this morning the backups seemed to be running.

Also, DA, my apologies for dropping this in General rather than Tech/Support section of Forum.

In the event I will wait a little longer before getting too tragic about it.
Reason I disabled Plugins though was because I suspected Secure Image anti-Spam system might be interfering with the SQL authentication.

Also, at one point I both RESET MySQL and Restored a Backup dated 19th May.

Using a shotgun sometimes gets ducks.

Thanks anyway.
 
The features page isn't as clear as I'd expect. Will installing it mean admin level backup/restore will automatically use it?

How about reseller level? User level?

How about System Backup?

Thanks.

Jeff, it should be used everywhere (in all of the places you mentioned) :)
 
Other than the possibility it would slow down the server, are there any downsides?

I seem tor emember that Backups intentionally use less resources than they could. Before trying this, or in addition to trying this, might it be a good idea to change the amount of resources a backup could use?

Or am I just confused?

Even with "nice" (http://www.directadmin.com/features.php?id=1179) to slow it down, it would work much faster, as it would use all CPU cores, not just a single thread. Talking about "ionice" - yes, there wouldn't be a lot of benefit in that case, because then it's HD, which limits the speed, not CPU.
 
If I recall correctly, Admin level Reseller backup uses nice, so I suppose I'll give it a try :).

Thanks.
