[Solved] Backup and restore question

I run a backup sucessfully:

Code:
 find . | backup -ivqf/dev/rmt0

I want to make sure I can restore, so I change to a test directory and try this:

Code:
restore -rvqf /dev/rmt0

However, we fail with this error:

Code:
New volume on /dev/rmt0:
Cluster size is 51200 bytes (100 blocks).
The volume number is 1.
The backup date is: Mon Feb 25 11:36:47 EST 2013
Files are backed up by name.
The user is root.
x            0 .
x        10240 ./testfile1
restore: 0511-138 Cannot write to file ./testfile2.
Restore : A system call received a parameter that is not valid.

Here's the directory listing

Code:
# ls -l
total 2098208
-rw-r--r--    1 root     system        10240 Feb 20 03:00 testfile1
-rw-r--r--    1 root     system   1073741312 Feb 25 12:29 testfile2

testfile1 was restored correctly.
testfile2 original size is 52758169600

Thanks for any help you can offer.

Both the source directory and the target directory, in this case, is on NFS share on a NAS.

I have a backup process on an AIX 6.1 box that writes files to the NFS share. I would like to backup them up to tape from an AIX 7.1 partition.

To get more information about my problem, I tried copying the files from the source directory to the test restore directory.

Code:
 cp source/* test
cp : 0653-447 Requested a write of 4096 bytes, but wrote only 3584.
cp : 0653-447 Requested a write of 4096 bytes, but wrote only 3584.
cp : 0653-447 Requested a write of 4096 bytes, but wrote only 3584.

I changed the max file size by editing the /etc/security/limits file.

I have absolutely no experience with AIX, but a post that I read in another thread may be relevant: from AIX & TAR related stuff , specifically the chuser/fsize advice.

It works much better after changing the max file size.

Thanks!

Good point!

Good idea on AIX after install is to run this command:


Code:
chuser fsize=-1 cpu=-1 data=-1 stack=-1 core=-1 rss=-1 root

This sets all ulimt settings to unlimited for root in /etc/security/limits
