Iterate array using loop over ssh

A simple script:

Code:
#!/bin/bash
test=test
test1=(test1 test2 test3)
echo ${test1[*]}
ssh server 'echo '$test'; echo '${test1[*]}' ; echo '${test1[1]}' ; for m in $(seq 1 $(echo '${test1[*]}' | tr " " "\n" | wc -l)); do echo $m ; echo '${test1[$m]}'; done'

Here is the result:

Code:
test1 test2 test3
testing
test
test1 test2 test3
test2
1
test1
2
test1 ***this should be "test2"
3
test1 ***this should be "test3"

Why is it not being iterated as expected?

I read somewhere that ssh doesn't know about the variables, etc etc. Then why can I see that "echo ${test1[*]}" iterates correctly?

BUMMER Smilie I really need this Smilie

Can you guys help me out?

**EDIT: Forgot the CODE tags, sorry Smilie

bup-restore(1)						      General Commands Manual						    bup-restore(1)

NAME
bup-restore - extract files from a backup set SYNOPSIS
bup restore [--outdir=outdir] [-v] [-q] DESCRIPTION
bup restore extracts files from a backup set (created with bup-save(1)) to the local filesystem. The specified paths are of the form /branch/revision/path/to/file. The components of the path are as follows: branch the name of the backup set to restore from; this corresponds to the --name (-n) option to bup save. revision the revision of the backup set to restore. The revision latest is always the most recent backup on the given branch. You can dis- cover other revisions using bup ls /branch. /path/to/file the original absolute filesystem path to the file you want to restore. For example, /etc/passwd. Note: if the /path/to/file is a directory, bup restore will restore that directory as well as recursively restoring all its contents. If /path/to/file is a directory ending in a slash (ie. /path/to/dir/), bup restore will restore the children of that directory directly to the current directory (or the --outdir). If the directory does not end in a slash, the children will be restored to a subdirectory of the current directory. See the EXAMPLES section to see how this works. OPTIONS
-C, --outdir=outdir create and change to directory outdir before extracting the files. -v, --verbose increase log output. Given once, prints every directory as it is restored; given twice, prints every file and directory. -q, --quiet don't show the progress meter. Normally, is stderr is a tty, a progress display is printed that shows the total number of files restored. EXAMPLE
Create a simple test backup set: $ bup index -u /etc $ bup save -n mybackup /etc/passwd /etc/profile Restore just one file: $ bup restore /mybackup/latest/etc/passwd Restoring: 1, done. $ ls -l passwd -rw-r--r-- 1 apenwarr apenwarr 1478 2010-09-08 03:06 passwd Restore the whole directory (no trailing slash): $ bup restore -C test1 /mybackup/latest/etc Restoring: 3, done. $ find test1 test1 test1/etc test1/etc/passwd test1/etc/profile Restore the whole directory (trailing slash): $ bup restore -C test2 /mybackup/latest/etc/ Restoring: 2, done. $ find test2 test2 test2/passwd test2/profile SEE ALSO
