Large Backups Fail
-
Hi!
I have a website, some 1400MB of files and 25MB database. When I try to perform a full backup it breaks. First, it gives me errors while trying to compress files that have very long filenames. That can’t be avoided and I think that is OK. After that, it stops on around 70%, lags for 2 minutes or so (you don’t see it in the log file) and gives me “Backup archive created.” message. Later on, when I downloaded the backup archive manually via FTP I realized that there are many files missing from the archive. After that, It tries to upload the archive to Dropbox, goes through to around 10%, lags for a few minutes, restarts, uploads another 10% and does this 3 times until it breaks.. I tried excluding the complece wp-content folder so there was only some 20MB left to backup and everything went fine. I installed the plugin and successfully backed up another website on the same server but that website takes around 200MB and 5MB database.
Could there be a problem with some PHP limit or anything else?
Any Ideas?Here’s the log file (I replaced all the links and personal data with XXXX and replaced the repetitive errors with . just to make the log shorter and easier to read)
