5. em restor DR make sure that there is sufficient disk space for the creation of large recovery logs from the Agent and other possible logging or auditing from the operating system File level logging on a setup containing a large file system can generate a large log which can potentially fill up the available or allocated disk space If the logs are on the same partition as the root file system this may prevent the OS from booting 19353 An NFS backup Job for a mounted file system will fail if the NFS mount is disconnected at run time The error messages for this failure do not explain that the problem is related to NFS 19215 When you restore a very large number of files to an alternate location you may run out of inodes for the file system This stops the restore process from responding You must kill the VV process and defunct processes may remain Truncated restore logs may also result The logs will indicate that there is no space left on the device but this might not be true Becaus ach file consumes an inode you cannot restore additional files regardless of how much space is available Recommendation Allocate more inodes for the destination file system 18967 The command line log viewer xlogcat uses the default language that you select during installation unless the LANG environment variable indicates a different supported language For example if German de DE is your selected
6. l way for your distribution Certain file systems and directories ar xcluded from backups These include the dev device directory including the devpts file system at dev pts boot directory var run directory and the proc file system usually at proc In Linux kernel version 2 6 there is now the sysfs file system to represent the system hardware devices and drivers usually at sys This is also excluded from backups Note On a complete system backup dev and proc directories are NOT backed up The Linux Agent only protects these locations under their default names These files must be restored to an alternative location and replaced manually if necessary as automatic replacement may leave the operating system in an unusable state When restoring Linux system files the boot loader should be reconfigured to find the restored operating system files and kernel in their current positions on the hard drive When using GNU GRUB http www gnu org software grub follow the instructions from the GRUB user manual for installing GRUB natively http www gnu org software grub manual grub html Installation For other boot loaders refer to the manual provided by your vendor By default chkconfig does not include VVAgent in the list of services that it manages If you add VVAgent to chkconfig the default run levels become 3 and 5 Recommendation Use 3 and
