Some questions about storage spaces

hi all,

i'm thinking of setting storage pool on windows server 2012 essentials, reading across internet there things want (double) check.

my plan start 2 3tb drives (2 way mirroring) , expand afterwards if necessary. main questions when run out of space.

1) had hoped when 2 disks got full, add 1 more disk , let system take care of rest, read that's not case , i'll have add 2 disks instead of 1 ?

2) let's , have added 2 disks after while (resulting in 4 disks in total). next time run out of space able add 2 more or have add 4 more ? (so 4 6 or have go 4 8 disks)
have assumed 2, this text here made me doubt:
quote:
"when comes mirror spaces, have take account both number of columns , number of data copies. example, two-way mirror created 4 physical disks figure 10. numberofdatacopies equals 2, , numberofcolumns equals 2. number of disks needed extend virtual disk can found using following formula:
numberofdatacopies * numberofcolumns

2 * 2 = 4"

however starting 2 disks originally, maybe it's not issue , can add 2 disks second time expand (from 4 6 disks) ?

3) let's want replace existing pair of disks bigger ones (for example 2 3tb disks). can remove 1 3tb disk , replace 4tb disk, wait pool synchronize next disk , pull second 3tb disk , replace 4tb disk ? work without issues ?

4) can use storage pool store client backups , preferably server backups ?

thank in advance advice,

[satish]: need understand mirror needs couple of underlying physical disks. if 1 disk full , if space carved out of disk mirror need 2 disks.

2) [satish]: need 2 disks extend this.

3) let's want replace existing pair of disks bigger ones (for example 2 3tb disks). can remove 1 3tb disk , replace 4tb disk, wait pool synchronize next disk , pull second 3tb disk , replace 4tb disk ? work without issues ?

[satish]: can create 4tb disk hot spare disk. once original disk goes disk replacement disk. once resynchronized can add 4tb disk hot-spare , remove 2nd 3tb disk.

4) can use storage pool store client backups , preferably server backups ?

yes. backup has happen on virtual disk.

do let me know if helps,

regards

satish
