Resolved Backup skip files with "Argument list too long" error

[Pascal_Netenvie]

Hi,
On a Plesk 12.0.18u96 on Debian 7.11 i have this message in backup log every night for one vhost :

Not all the data was backed up into /var/lib/psa/dumps/domains/mydomain.com successfully. sh: 1: /bin/tar: Argument list too long

How to debug and solve that please ?

Regards !

This is happening when you have too many files in a folder, like 100000 or more. This is a tar (and not just) issue, cannot read all files. Try to see in which folder you have that many files and if I presume well it is a cache folder. Try to see how you can write a script to delete older files.

Hi Pascal_Netenvie,

such issues appear, when you reach server configuration limits. Use for example the command

echo $(( $(getconf ARG_MAX) - $(env | wc -c) ))

... to display your current setting on your server.

You might as well consider to EXCLUDE folders/files in your backup - settings.

Thx Ivalics, it was this.
A cron task was generating a file every 3 min at vhost root so we had hunders thousands of useless files ... this is fixed and backup run ok.
