backup: 0511-432 A write error occurred: A file cannot be larger than the value set by ulimit

原因：由於檔案系統最大空間的限制，修改這個限制

修改檔案：/etc/security/limits

# more limits

*

* Sizes are in multiples of 512 byte blocks, CPU time is in seconds

*

* fsize - soft file size in blocks

* core - soft core file size in blocks

* cpu - soft per process CPU time limit in seconds

* data - soft data segment size in blocks

* stack - soft stack segment size in blocks

* rss - soft real memory usage in blocks

* nofiles - soft file descriptor limit

* fsize_hard - hard file size in blocks

* core_hard - hard core file size in blocks

* cpu_hard - hard per process CPU time limit in seconds

* data_hard - hard data segment size in blocks

* stack_hard - hard stack segment size in blocks

* rss_hard - hard real memory usage in blocks

* nofiles_hard - hard file descriptor limit

*

* The following table contains the default hard values if the

* hard values are not explicitly defined:

*

* Attribute Value

* ========== ============

* fsize_hard set to fsize

* cpu_hard set to cpu

* core_hard -1

* data_hard -1

* stack_hard 8388608

* rss_hard -1

* nofiles_hard -1

*

* NOTE: A value of -1 implies "unlimited"

default:

fsize = 2097151

core = 2097151

cpu = -1

data = 262144

rss = 65536

stack = 65536

nofiles = 2000

root:

fsize=-1

daemon:

bin:

sys:

adm:

uucp:

guest:

nobody:

lpd:

esaadmin:

stack = 393216

stack_hard = 393216

在root:下增加一行：fsize=-1　　　意思就是root使用者下無限制檔案大小

重新啟動系統後才能生效
